Description

Removes the cuda:0-only restriction in FabricFrameView. USDRT SelectPrims now accepts any CUDA device index, so Fabric acceleration runs on the simulation device (e.g., cuda:1) instead of silently falling back to the slower USD path. This unblocks distributed training where each process is pinned to a specific GPU.

The change itself is small (drops the device guard in __init__, the assertion in _initialize_fabric, and the _fabric_supported_devices allowlist). The bulk of the diff is multi-GPU test coverage — three cuda:1-parameterized tests guarded by a new multi_gpu pytest marker, plus a dedicated CI job on the multi-GPU runner so regressions show up on PRs that touch FabricFrameView.

The skip-vs-fail logic in _skip_if_unavailable is intentional:

On a developer workstation with a single GPU, cuda:1 tests pytest.skip with a warning so local runs stay green.
In CI (GITHUB_ACTIONS=true), a missing cuda:1 becomes pytest.fail so a misconfigured runner is caught immediately rather than silently green-lighting every PR.

Stacked on: isaac-sim#5380. Merge that one first; this PR contains only the multi-GPU enablement on top of it.

Type of change

New feature (non-breaking change which adds functionality)

cuda:0 continues to work exactly as before; cuda:1+ now also works instead of silently falling back to USD. No public API surface changed.

Checklist

I have read and understood the contribution guidelines
I have run the pre-commit checks with ./isaaclab.sh --format
I have made corresponding changes to the documentation

Note on the changelog item: this PR uses a fragment file at source/isaaclab_physx/changelog.d/feat-frame-view-enable-mgpu.rst per the new fragment-based changelog system (isaac-sim#5434). CHANGELOG.rst and config/extension.toml are intentionally not edited directly — the nightly CI workflow compiles them from fragments.

Test plan

Three new tests, all marked @pytest.mark.multi_gpu and parameterized with ["cuda:1"]:

test_fabric_cuda1_world_pose_roundtrip — set_world_poses → get_world_poses returns the same values on a non-primary CUDA device.
test_fabric_cuda1_no_usd_writeback — Fabric writes on cuda:1 do not write back to USD (atol=0.0 — equality, not approximate).
test_fabric_cuda1_scales_roundtrip — covers the set_scales write path on cuda:1, since both Fabric write paths now run on self._device.

A new CI job, test-fabric-multi-gpu, runs in .github/workflows/test-multi-gpu.yaml on the existing [self-hosted, linux, x64, gpu, multi-gpu] runner. The job pre-flights with ./isaaclab.sh -p -c "import torch; print(torch.cuda.device_count())" and fails loudly with ::error:: if the runner regresses to a single GPU. Triggered automatically on PRs that touch source/isaaclab_physx/isaaclab_physx/sim/views/fabric_frame_view.py or its test file.

To verify locally on a multi-GPU machine:

./isaaclab.sh -p -m pytest -m multi_gpu \
    source/isaaclab_physx/test/sim/test_views_xform_prim_fabric.py -v

To verify the cuda:0 path is unchanged:

./isaaclab.sh -p -m pytest -m "not multi_gpu" \
    source/isaaclab_physx/test/sim/test_views_xform_prim_fabric.py -v

…ic_write (isaac-sim#5380) ## Summary Replace the `sync_usd_on_fabric_write` workaround in `FabricFrameView` with proper `PrepareForReuse()` calls on the Fabric `PrimSelection`. This tells the renderer (FSD/Storm) that Fabric data has changed, so the next rendered frame reflects updated transforms — eliminating the need to copy Fabric writes back to USD. ## Motivation The existing `sync_usd_on_fabric_write` flag worked by mirroring every Fabric write back to USD, which defeated the performance benefits of Fabric. With `PrepareForReuse()`, the rendering pipeline is properly notified of Fabric data changes without any USD writeback. Additionally, the old code incorrectly fell back to USD for CPU devices — Warp handles CPU Fabric buffers correctly, so the fallback was unnecessary. This addresses two of the issues raised in @pbarejko Piotr's review of PR isaac-sim#4923: - **Issue #1** (USD write-back): Fabric writes no longer sync back to USD - **Issue isaac-sim#4** (PrepareForReuse): Renderer notification via `PrepareForReuse()` instead of USD writeback ## Changes ### Core (FabricFrameView) - Call `_prepare_for_reuse()` in write paths (`set_world_poses`, `set_scales`) to notify the renderer - Remove `sync_usd_on_fabric_write` parameter (accepted via `**kwargs` for backward compat) - Remove incorrect CPU/device fallback warnings — Warp handles CPU Fabric buffers correctly - Add `_rebuild_fabric_arrays()` for topology change recovery when `PrepareForReuse()` returns True, with assertion guarding the prim-count invariant ### Camera - Remove `sync_usd_on_fabric_write=True` from FrameView construction in `camera.py` ## Benchmark Results 1024 prims, 50 iterations, NVIDIA L40 GPU: | Operation | USD (ms) | Fabric (ms) | Speedup | |---|---|---|---| | Get World Poses | 14.71 | 0.07 | **203x** | | Set World Poses | 40.75 | 0.16 | **259x** | | Interleaved Set→Get | 55.90 | 0.24 | **232x** | | Get Local Poses | 11.08 | 11.12 | 1.0x | | Set Local Poses | 16.14 | 16.28 | 1.0x | Local poses fall back to USD (expected — Fabric only accelerates world poses via `omni:fabric:worldMatrix`). ## Tests Added | Test | What it validates | |------|------------------| | `test_camera_pose_update_reflected_in_render` | Camera pose changes propagate to rendered depth (close vs far) for CPU/GPU, tiled/non-tiled | | `test_fabric_set_world_does_not_write_back_to_usd` | Fabric writes stay in Fabric, USD prim unchanged | | `test_set_world_updates_local` (xfail) | Documents Issue isaac-sim#5: `set_world_poses` doesn't update local pose in Fabric mode | ## Test Results | Test Suite | Passed | Skipped | Xfailed | Total | |---|---|---|---|---| | Fabric contract tests (`test_views_xform_prim_fabric.py`) | 17 | 16 | 1 | 34 | | USD contract tests (`test_views_xform_prim.py`) | 45 | 0 | 0 | 45 | | Camera render test (`test_tiled_camera.py`) | 8 | 0 | 0 | 8 | ## Type of change - Performance improvement (removes redundant USD writeback on Fabric operations) ## Checklist - [x] I have read and understood the [contribution guidelines](https://isaac-sim.github.io/IsaacLab/main/source/refs/contributing.html) - [x] I have run the [`pre-commit` checks](https://pre-commit.com/) with `./isaaclab.sh --format` - [ ] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] I have updated the changelog and the corresponding version in the extension's `config/extension.toml` file - [x] I have added my name to the `CONTRIBUTORS.md` or my name already exists there *No doc changes needed (parameter wasn't referenced in any docs)*

- Allow FabricFrameView to run on cuda:N for any N; USDRT SelectPrims no longer needs cuda:0. - Refactor the Fabric write path into a single _compose_fabric_transform helper shared by set_world_poses, set_scales, and the initial USD->Fabric sync, collapsing the sync to one kernel launch with one PrepareForReuse. - Replace the topology-invariant assert with RuntimeError so it survives python -O. - Add multi_gpu pytest marker plus cuda:1 unit-test coverage for both Fabric write paths, and run them in the existing test-multi-gpu CI job (one extra step, no new job).

The standard pytest invocation in CI runs the fabric test file without filtering on the ``multi_gpu`` marker, so the ``cuda:1`` tests get scheduled on every runner including the single-GPU ones. Previously ``_skip_if_unavailable`` hard-failed via ``pytest.fail`` whenever ``GITHUB_ACTIONS=true`` and the requested device was missing, on the theory that this would catch a misconfigured multi-GPU runner. In practice it just broke the standard CI: the dedicated ``test-fabric-multi-gpu`` workflow already pre-flights ``torch.cuda.device_count() >= 2`` before invoking pytest, so a genuinely misconfigured multi-GPU runner is already caught there. Always skip rather than fail when the requested ``cuda:N`` index isn't available. Drop the now-unused ``import os``.

# Description the camera config was importing `isaaclab_physx.renderers` because the default render_cfg was set to that config. this PR sets that to RendererConfig to remove the import, but provides a get_default_render_config method to the backend_utils to lazily import the config if needed. this is called __post_init__ on the camera config to replace the generic config as soon as possible to avoid downstream issues referencing the renderer config. this action can be moved to the factory if downstream references are cleaned up. ## Type of change - Refactor to remove imports in cfg class ## Checklist - [x] I have read and understood the [contribution guidelines](https://isaac-sim.github.io/IsaacLab/main/source/refs/contributing.html) - [x] I have run the [`pre-commit` checks](https://pre-commit.com/) with `./isaaclab.sh --format` - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] I have updated the changelog and the corresponding version in the extension's `config/extension.toml` file - [x] I have added my name to the `CONTRIBUTORS.md` or my name already exists there --------- Co-authored-by: nvsekkin <72572910+nvsekkin@users.noreply.github.com>

…ields (isaac-sim#5275) # Description Splits IsaacLab's USD-physics cfg classes into solver-common base classes and backend-specific subclasses, and refactors the writers (`modify_*_properties`, `spawn_rigid_body_material`) so that schema application is data-driven rather than hard-coded per-class. Prepares the schema layer for multi-backend support (PhysX today, Newton/Mjc next) without polluting base classes with silently-ignored fields or stamping backend-specific schemas onto prims that didn't opt in. ## Architecture Two layered concepts: 1. **Per-declaring-class routing.** Each cfg field's USD namespace is determined by the class that declares it (walking the MRO). Base-class fields write under `physics:*`; subclass fields write under their own namespace (`physxRigidBody:*`, etc.). When a `PhysxRigidBodyPropertiesCfg` instance is written, base fields still go under `physics:*` because `_usd_namespace` is read from the declaring class via `__dict__`, not via `getattr` (which would hit the subclass override). 2. **Per-field exceptions.** Some "universal physics" fields have no USD path except through a backend-namespaced attribute today (e.g., `disable_gravity` only exists at `physxRigidBody:disableGravity`). These are declared as `_usd_field_exceptions = {applied_schema: (namespace, [fields...])}` on the base class; the writer applies the exception schema only when one of the listed fields is non-None. The single helper `_apply_namespaced_schemas(prim, cfg, cfg_dict)` in `schemas.py` does both passes for every writer (rigid body, collision, articulation root, joint drive, mesh collision, rigid-body material). ## Design constraints **One cfg class per spawner slot.** Spawners (`UsdFileCfg`, `MeshCuboidCfg`, etc.) carry a single field for each property group: `rigid_props: RigidBodyBaseCfg | None`, `collision_props: CollisionBaseCfg | None`, `joint_drive_props: JointDriveBaseCfg | None`, etc. The user cannot pass two cfgs into the same slot, so the cfg class hierarchy must be **single-rooted per spawner field** — one base class per group, with backend-specific subclasses below. This rules out a "PhysX cfg sits next to a Newton cfg as siblings" design and drives several placement decisions: | Constraint | Consequence | |---|---| | Universal-physics fields must be reachable from any backend's cfg | Goes on the **base** class, not a sibling backend cfg. Users on Newton-only deployments can use `RigidBodyBaseCfg(disable_gravity=True)` without importing `isaaclab_physx`. | | A PhysX-namespaced field whose semantics are universal (e.g., `disable_gravity`) | Lives on the base but routes to the PhysX namespace via `_usd_field_exceptions`. The base stays backend-clean; the writer dispatches the PhysX write only when the field is non-None. | | Writer logic must not branch on cfg subclass | Every writer is the same code path regardless of subclass. The cfg metadata (`_usd_namespace`, `_usd_applied_schema`, `_usd_field_exceptions`) drives behavior; the writer is a pure data interpreter. | | Adding a new backend (Newton, Mjc) | Requires a new subclass with its own `_usd_namespace` / `_usd_applied_schema`. No spawner-side changes, no writer-side changes, no base-cfg-side changes. | | A field has multiple USD paths today (one PhysX-namespaced, one Newton-namespaced) | Belongs on the **PhysX subclass**, not the base. A future `NewtonArticulationRootPropertiesCfg` will own the same conceptual field on the Newton side. ("Rule 2" — e.g., `enabled_self_collisions`.) | | A field has only one USD path today, namespaced under PhysX, but the conceptual quantity is universal | Belongs on the **base** with an `_usd_field_exceptions` entry. ("Rule 1" — e.g., `disable_gravity`, `articulation_enabled`, `contact_offset`, `rest_offset`, `max_joint_velocity`.) When Newton ships its own native attribute, the exception namespace switches transparently with no API change. | ## Field placement ### Base (solver-common) classes — `physics:*` namespace via `UsdPhysics.*API` | Cfg class | Field | USD attribute | |---|---|---| | `RigidBodyBaseCfg` | `rigid_body_enabled` | `physics:rigidBodyEnabled` | | `RigidBodyBaseCfg` | `kinematic_enabled` | `physics:kinematicEnabled` | | `CollisionBaseCfg` | `collision_enabled` | `physics:collisionEnabled` | | `MassPropertiesCfg` | `mass` | `physics:mass` | | `MassPropertiesCfg` | `density` | `physics:density` | | `RigidBodyMaterialBaseCfg` | `static_friction` | `physics:staticFriction` | | `RigidBodyMaterialBaseCfg` | `dynamic_friction` | `physics:dynamicFriction` | | `RigidBodyMaterialBaseCfg` | `restitution` | `physics:restitution` | | `JointDriveBaseCfg` | `drive_type` | `drive:<axis>:physics:type` | | `JointDriveBaseCfg` | `max_force` | `drive:<axis>:physics:maxForce` | | `JointDriveBaseCfg` | `stiffness` | `drive:<axis>:physics:stiffness` | | `JointDriveBaseCfg` | `damping` | `drive:<axis>:physics:damping` | | `MeshCollisionBaseCfg` | `mesh_approximation_name` | `physics:approximation` (token) | | `ArticulationRootBaseCfg` | `fix_root_link` | (synthesizes `UsdPhysics.FixedJoint`) | `JointDriveBaseCfg` and `MeshCollisionBaseCfg` use the typed `UsdPhysics.DriveAPI` / `UsdPhysics.MeshCollisionAPI` accessors at the writer level (multi-instance namespace and `TfToken` with `allowedTokens`, respectively); all other base fields flow through the helper's per-class routing. ### PhysX subclasses — `physx*:*` namespaces, `Physx*API` schemas | Cfg class | `_usd_namespace` | `_usd_applied_schema` | Adds fields | |---|---|---|---| | `PhysxRigidBodyPropertiesCfg` | `physxRigidBody` | `PhysxRigidBodyAPI` | `linear_damping`, `angular_damping`, `max_linear_velocity`, `max_angular_velocity`, `max_depenetration_velocity`, `max_contact_impulse`, `enable_gyroscopic_forces`, `retain_accelerations`, solver iter counts, sleep / stabilization thresholds | | `PhysxCollisionPropertiesCfg` | `physxCollision` | `PhysxCollisionAPI` | `torsional_patch_radius`, `min_torsional_patch_radius` | | `PhysxArticulationRootPropertiesCfg` | `physxArticulation` | `PhysxArticulationAPI` | `enabled_self_collisions`, solver iter counts, sleep / stabilization thresholds | | `PhysxJointDrivePropertiesCfg` | `physxJoint` | `PhysxJointAPI` | (currently empty; reserved for future PhysX-only knobs) | | `PhysxRigidBodyMaterialCfg` | `physxMaterial` | `PhysxMaterialAPI` | `compliant_contact_stiffness`, `compliant_contact_damping`, `friction_combine_mode`, `restitution_combine_mode` | | `PhysxConvexHullPropertiesCfg` | `physxConvexHullCollision` | `PhysxConvexHullCollisionAPI` | `hull_vertex_limit`, `min_thickness` | | `PhysxConvexDecompositionPropertiesCfg` | `physxConvexDecompositionCollision` | `PhysxConvexDecompositionCollisionAPI` | hull / voxel / shrink-wrap tunables | | `PhysxTriangleMeshPropertiesCfg` | `physxTriangleMeshCollision` | `PhysxTriangleMeshCollisionAPI` | `weld_tolerance` | | `PhysxTriangleMeshSimplificationPropertiesCfg` | `physxTriangleMeshSimplificationCollision` | `PhysxTriangleMeshSimplificationCollisionAPI` | `simplification_metric`, `weld_tolerance` | | `PhysxSDFMeshPropertiesCfg` | `physxSDFMeshCollision` | `PhysxSDFMeshCollisionAPI` | `sdf_margin`, `sdf_narrow_band_thickness`, `sdf_resolution`, etc. | ### `_usd_field_exceptions` table These fields are declared on a *base* class but the only USD path today goes through a non-base namespace. Each entry says: "if any listed field on this cfg is non-None, apply the exception schema and write that one attribute under the exception namespace." All other fields on the cfg follow the per-declaring-class routing rule. | Base cfg class | Exception schema | Namespace | Field(s) | Why on the base | |---|---|---|---|---| | `RigidBodyBaseCfg` | `PhysxRigidBodyAPI` | `physxRigidBody` | `disable_gravity` | Per-body gravity exclusion is universal physics; PhysX honors per-body, Newton consumes the same attribute via the bridge resolver (scene-level today; per-body fix is a Newton-side kernel change, not a cfg-API change) | | `CollisionBaseCfg` | `PhysxCollisionAPI` | `physxCollision` | `contact_offset`, `rest_offset` | Collision-pair generation distance and rest gap are universal physics; Newton importer consumes both via PhysX bridge to populate `Model.shape_collision_radius` / `_thickness` (`import_usd.py:2104, 2111`) | | `ArticulationRootBaseCfg` | `PhysxArticulationAPI` | `physxArticulation` | `articulation_enabled` | PhysX honors at sim time; IsaacLab Newton wrapper reads it as a spawn-time guard at `rigid_object.py:1035`. Universal user-facing intent | | `JointDriveBaseCfg` | `PhysxJointAPI` | `physxJoint` | `max_joint_velocity` | Sole USD path to `Model.joint_velocity_limit` in Newton (no `newton:*` equivalent today). The exception namespace switches transparently when Newton ships `newton:maxJointVelocity` as a registered applied API | When any exception field is non-None, the corresponding `Physx*API` schema is applied to the prim. When all exception fields are None, no PhysX schema is stamped — Newton-targeted prims authored from `*BaseCfg` stay free of PhysX schemas they didn't opt in to. ## Field renames (with deprecation aliases) To enforce the convention that python `snake_case` cfg field names map identity-style to USD `camelCase` attribute names, two legacy fields were renamed. Both keep the old name as a deprecation alias forwarded via `__post_init__` (emits `DeprecationWarning`, scheduled for removal in 5.0). | Old name | New name | USD attribute | |---|---|---| | `JointDriveBaseCfg.max_velocity` | `max_joint_velocity` | `physxJoint:maxJointVelocity` | | `JointDriveBaseCfg.max_effort` | `max_force` | `drive:<axis>:physics:maxForce` | ## Type of change - New feature (non-breaking change which adds functionality) - Breaking change (existing functionality will not work without user modification) The split is non-breaking at the spawner-cfg level — every base-class type accepts any subclass via polymorphism, and every legacy `RigidBodyPropertiesCfg` / `JointDrivePropertiesCfg` / `CollisionPropertiesCfg` / `ArticulationRootPropertiesCfg` / `MeshCollisionPropertiesCfg` / `RigidBodyMaterialCfg` / `FixedTendonPropertiesCfg` / `SpatialTendonPropertiesCfg` import path continues to work via deprecation-alias subclasses and `__getattr__` shims on `isaaclab.sim`, `isaaclab.sim.schemas`, and `isaaclab.sim.schemas.schemas_cfg`. Direct attribute access to the renamed fields still works through deprecation aliases. Removal scheduled for 5.0. The breaking aspect: cfg classes in `isaaclab_physx.sim.schemas` and `isaaclab_physx.sim.spawners.materials` are physically relocated. Anyone importing from internal paths (rather than `isaaclab.sim`) needs to update. ## Migration ```python # Before import isaaclab.sim as sim_utils rigid_props = sim_utils.RigidBodyPropertiesCfg(disable_gravity=True, linear_damping=0.1) joint_props = sim_utils.JointDrivePropertiesCfg(max_effort=80.0, max_velocity=5.0) collision_props = sim_utils.CollisionPropertiesCfg(contact_offset=0.02, torsional_patch_radius=1.0) material = sim_utils.RigidBodyMaterialCfg(static_friction=0.7, compliant_contact_stiffness=1000.0) # After (PhysX-targeted) import isaaclab.sim as sim_utils from isaaclab_physx.sim.schemas import ( PhysxRigidBodyPropertiesCfg, PhysxJointDrivePropertiesCfg, PhysxCollisionPropertiesCfg, ) from isaaclab_physx.sim.spawners.materials import PhysxRigidBodyMaterialCfg rigid_props = PhysxRigidBodyPropertiesCfg(disable_gravity=True, linear_damping=0.1) joint_props = PhysxJointDrivePropertiesCfg(max_force=80.0, max_joint_velocity=5.0) collision_props = PhysxCollisionPropertiesCfg(contact_offset=0.02, torsional_patch_radius=1.0) material = PhysxRigidBodyMaterialCfg(static_friction=0.7, compliant_contact_stiffness=1000.0) # After (Newton-targeted — base classes only, no PhysX schemas applied) from isaaclab.sim.schemas import RigidBodyBaseCfg, JointDriveBaseCfg, CollisionBaseCfg from isaaclab.sim.spawners.materials import RigidBodyMaterialBaseCfg rigid_props = RigidBodyBaseCfg(disable_gravity=True) # only base + exception fields available joint_props = JointDriveBaseCfg(max_force=80.0, max_joint_velocity=5.0) material = RigidBodyMaterialBaseCfg(static_friction=0.7) ``` Spawner type annotations remain unchanged — they accept any subclass via polymorphism. ## Internal helper ```python def _apply_namespaced_schemas(prim, cfg, cfg_dict): # 1. Per-field exceptions: pop listed fields, apply exception schema if any non-None, # write under exception namespace. # 2. Per-declaring-class routing: walk MRO to find each remaining field's owner class; # write under that class's _usd_namespace; apply that class's _usd_applied_schema. ``` Used by all five `modify_*_properties` writers and `spawn_rigid_body_material`. Replaced ~125 lines of duplicated gating logic with a single ~30-line helper. ## Side change: configclass `source/isaaclab/isaaclab/utils/configclass.py:_process_mutable_types` now detects string-form `ClassVar` annotations under PEP 563 (`from __future__ import annotations`) so it doesn't wrap `ClassVar[dict]` defaults in `field(default_factory=...)`. Matches Python stdlib `dataclasses` semantics.

Zero new regressions; +123 passing tests vs. earlier state. - [x] `./isaaclab.sh -f` (pre-commit) clean. ## Supersedes Together with isaac-sim#5276, supersedes isaac-sim#4847 and isaac-sim#5203 with a cleaner schema-layer design. ## Checklist - [x] I have read and understood the [contribution guidelines](https://isaac-sim.github.io/IsaacLab/main/source/refs/contributing.html) - [x] I have run the [`pre-commit` checks](https://pre-commit.com/) with `./isaaclab.sh --format` - [x] I have made corresponding changes to the documentation (changelog fragments under `source/isaaclab/changelog.d/`) - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] I have updated the changelog (fragment-based system) and the corresponding version in the extension's `config/extension.toml` file - [x] I have added my name to the `CONTRIBUTORS.md` or my name already exists there --------- Co-authored-by: ooctipus <zhengyuz@nvidia.com>

Kit's CLI parser reads sys.argv directly at startup and segfaults on pytest flags that collide with its own short options. Running pytest -m multi_gpu source/isaaclab_physx/test/sim/test_views_xform_prim_fabric.py crashes during collection because Kit sees ``-m multi_gpu`` and exits with ``Ill formed parameter: -m`` followed by SIGSEGV (exit code 245) inside ``simulation_app._start_app``. Strip sys.argv to argv[0] before instantiating AppLauncher. The test file takes no CLI arguments of its own, mirroring the broader pattern used by ``test_tiled_camera_env.py`` which assigns ``sys.argv[1:] = args_cli.unittest_args`` after argparse.

## Summary Bumps the Newton pin to [`v1.2.0rc2`](https://pypi.org/project/newton/1.2.0rc2/), which pulls in IsaacLab-relevant fixes plus the upstream tendon-scoping fix. ## What's new in Newton v1.2.0rc2 vs IsaacLab's current pin (`a27277e`) The current IsaacLab Newton pin is from late April; v1.2.0rc2 is the latest release-candidate cut. Notable fixes pulled in: - **[newton-physics/newton#2659](newton-physics/newton#2659 \"Scope USD custom-frequency parsing\" — `parse_usd` now scopes the custom-frequency walk to `root_path` natively. - **[newton-physics/newton#2678](newton-physics/newton#2678 Regression fix. - **[newton-physics/newton#2720](newton-physics/newton#2720 `SolverKamino` reset under `world_mask`. - **[newton-physics/newton#2710](newton-physics/newton#2710 VRAM leak fix on example reset. - Plus 16 other smaller fixes between rc1 and rc2. ## Required dep bumps Newton 1.2.0rc2's \`pyproject.toml\` requires: - \`warp-lang==1.13.0\` - \`mujoco==3.8.0\` (was 3.6.0) - \`mujoco-warp==3.8.0.1\` (was 3.6.0) Pins updated in: | File | Change | |---|---| | \`source/isaaclab/setup.py\` | \`warp-lang==1.12.0\` → \`==1.13.0\`; \`mujoco==3.6.0\` → \`==3.8.0\`; \`mujoco-warp==3.6.0\` → \`==3.8.0.1\` | | \`source/isaaclab_newton/setup.py\` | mujoco / mujoco-warp bumps; Newton pin → \`v1.2.0rc2\` | | \`source/isaaclab_visualizers/setup.py\` | 3× Newton pin → \`v1.2.0rc2\` | | \`tools/wheel_builder/res/python_packages.toml\` | All four pins mirrored | ## Code adapts \`warp-lang\` 1.13 removed the \`wp.math\` namespace.

isaac-sim#5538) ## Summary Two unrelated CI breakages on develop, bundled here so develop turns green in one PR. ### 1. Skip the failing viewergl test `test_cartpole_newton_visualizer_viewergl_rgb_motion[physx,newton]` started returning all-black frames on develop after `nvcr.io/nvidian/isaac-sim:latest-develop` flipped to a Kit 110.1.1 + USD 25.11 base. The failure has been deterministic across multiple PRs (isaac-sim#5523, isaac-sim#5495, isaac-sim#5408, …). Investigation so far has ruled out: - PR isaac-sim#5521 (revert in isaac-sim#5539 still failed) - Newton 1.0 → 1.2.0rc2 viewer code regression (only 7-line addition; ViewerGL alone yields 1.08M nonzero pixels) - warp 1.12 → 1.13 RegisteredGLBuffer ABI (byte-identical) - Module-load side effects of `isaaclab_physx.renderers` - CUDA-GL interop (PR isaac-sim#5540 diagnostic confirms direct CPU FBO readback also returns zeros, with `GL_NO_ERROR`) - GL context-currency (PR isaac-sim#5541 H6 attempt: still fails) - GL/CUDA sync (PR isaac-sim#5542 H4 attempt: still fails) Diagnostic output (PR isaac-sim#5540 v2): ``` [VIZDIAG] fbo=c_uint(8) pbo=None size=600x600 [VIZDIAG] glGetError before: GL_NO_ERROR [VIZDIAG] CPU-readback: nonzero=0/1080000 max=0 err=GL_NO_ERROR [VIZDIAG] PBO-result: nonzero=0/1080000 max=0 ``` The FBO itself is empty — Newton's pyglet/EGL renderer is not depositing pixels under Kit 110.1.1, even though `tiled_camera_rgb_non_black` (Kit RTX path) on the same env passes. Underlying root cause still being chased; this PR ships the skip to unblock develop. ### 2. Fix warp intersphinx 404 in docs build `https://nvidia.github.io/warp/objects.inv` started returning 404 — Warp's `objects.inv` only lives at `/stable/` and `/latest/` now. With Sphinx's `warnings_treated_as_errors`, the broken intersphinx fetch fails the docs build on every PR. Pinning to `/stable/` (matches the existing PyTorch `/docs/2.11/` workaround pattern in the same file). Verified `https://nvidia.github.io/warp/stable/objects.inv` returns 200. ## Test plan - [x] CI `isaaclab_visualizers` on this branch — was passing earlier with the skip; will re-verify with the bundled docs fix - [ ] CI `Build Latest Docs` on this branch — must turn green (was failing on every recent PR before this fix) ## Re-enable plan Once the underlying viewergl bug is identified and fixed, drop the `@pytest.mark.skip` decorator and remove the `jichuanh-disable-viewergl-flaky.skip` fragment.

Summary - Fixes OvPhysX backend compatibility with the upcoming ovphysx 0.4 API by using `active_cuda_gpus` and explicit DirectGPU Carbonite settings when supported, while preserving the older `gpu_index` constructor path. - Fixes CPU-only OvPhysX tensor binding reads into GPU-backed articulation buffers. - Uses raw Warp buffers for OvPhysX articulation write views instead of `ProxyArray` wrappers. - Adds the `ovphysx` physics preset to the cartpole camera presets task.

It also enables the cartpole camera presets task to select the `ovphysx` physics preset. The OvPhysX manager now detects the new constructor surface and passes explicit DirectGPU settings for GPU simulations. Older public wheels that still use `gpu_index` keep the previous constructor path.

# Description Fixed bugs: - [NVBug 6122918] - Grammar in installation docs (``these dependency`` -> ``these dependencies``; drop redundant ``guides`` after ``:ref:`how-to```). - [NVBug 6125106] - Add an ``Environment setup`` section to the kit-less install page so it does not jump from ``git clone`` straight to ``./isaaclab.sh --install``. - [NVBug 6125054] - Relax ``starlette==0.49.1`` -> ``>=0.46.0,<0.50`` so ``isaaclab[isaacsim,all]==3.0.0`` resolves alongside ``isaacsim==6.0.0.0`` (transitively requires ``starlette<0.49.0``). - [NVBug 6122885] - Bump recommended driver versions on the installation index to the Beta2 POR (Linux ``580.95.05``, Spark ``580.142``, Windows ``581.42.00``). ## Type of change - Bug fix (non-breaking change which fixes an issue) - Documentation update ## Checklist - [x] I have read and understood the [contribution guidelines](https://isaac-sim.github.io/IsaacLab/main/source/refs/contributing.html) - [x] I have run the [``pre-commit`` checks](https://pre-commit.com/) with ``./isaaclab.sh --format`` - [x] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works - [x] I have added a changelog fragment under ``source/<pkg>/changelog.d/`` for every touched package (do **not** edit ``CHANGELOG.rst`` or bump ``extension.toml`` -- CI handles that) - [x] I have added my name to the ``CONTRIBUTORS.md`` or my name already exists there --------- Co-authored-by: Antoine RICHARD <antoiner@nvidia.com>

…m#5544) # Description The `isaaclab.sim.spawners.from_files` module imports `fcntl` unconditionally at module load. `fcntl` is Unix-only, so on Windows the import fails with: ``` ModuleNotFoundError: No module named 'fcntl' ``` This breaks **any** Windows usage of the spawner — including single-GPU runs that never take the lock path. Reproducer reported by a user (IsaacLab `develop` @ `b258e87`, IsaacSim `6.0.0rc41`): ``` python scripts/reinforcement_learning/rl_games/train.py --task=Isaac-Cartpole-v0 --headless --video --video_length 100 --video_interval 500 --max_iterations 5 ``` `fcntl` was introduced in isaac-sim#5032 to serialize USD download/stage composition across distributed ranks (preventing segfaults in `Sdf_CrateFile::_MmapStream::Read` on shared cached USD files). The intent is correct — only the implementation is Unix-only. ## Change - Replace `fcntl.flock` with [`filelock.FileLock`](https://pypi.org/project/filelock/), which uses `fcntl` on POSIX and `msvcrt` on Windows. - Use `contextlib.nullcontext` for the single-rank path so the lock file is only created when actually needed (i.e., `LOCAL_WORLD_SIZE > 1`). - Drop the manual `try/finally` and the `# noqa: SIM115` on the bare `open(...)` — the `with FileLock(...)` form is exception-safe. - Declare `filelock` in `source/isaaclab/setup.py::INSTALL_REQUIRES`. It was previously only transitively available via `transformers` → `huggingface_hub`; making it a direct dep so we don't depend on a transitive chain that could change. The lock semantics are unchanged: an exclusive advisory lock on `<tempdir>/isaaclab_usd_spawn.lock`, held only while `LOCAL_WORLD_SIZE > 1`. Original lock implementation: @ooctipus (isaac-sim#5032) — tagging for review since this changes the locking primitive. ## Type of change - Bug fix (non-breaking change which fixes an issue) ## Screenshots N/A — import-time failure on Windows; no UI surface. ## Checklist - [x] I have read and understood the [contribution guidelines](https://isaac-sim.github.io/IsaacLab/main/source/refs/contributing.html) - [x] I have run the [`pre-commit` checks](https://pre-commit.com/) with `./isaaclab.sh --format` - [ ] I have made corresponding changes to the documentation (N/A — internal change) - [x] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works — the failure is `import fcntl` at module load on Windows; a regression test would require a Windows CI runner, which IsaacLab does not currently exercise. Locally verified the module imports and `FileLock` resolves to `filelock._unix.UnixFileLock` on Linux (and would resolve to `WindowsFileLock` on Windows). - [x] I have added a changelog fragment under `source/<pkg>/changelog.d/` for every touched package (do **not** edit `CHANGELOG.rst` or bump `extension.toml` — CI handles that) - [x] I have added my name to the `CONTRIBUTORS.md` or my name already exists there

# Description OVRTX renderer relies on Warp. In some instances, i.e. unit tests, the ovrtx integration layer can fail with following error: ```python else: try: if torch_device.type == "cuda": > return warp._src.context.runtime.cuda_devices[torch_device.index] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ E AttributeError: 'NoneType' object has no attribute 'cuda_devices' ovphysx-ovrtx/lib/python3.12/site-packages/warp/_src/torch.py:41: AttributeError ``` This problem is because warp runtime isn't initialized, by importing `import isaaclab.utils.warp` module we ensure warp runtime is initialized. Fixes # (issue)  ## Type of change  - Bug fix (non-breaking change which fixes an issue) - New feature (non-breaking change which adds functionality) - Breaking change (existing functionality will not work without user modification) - Documentation update ## Screenshots Please attach before and after screenshots of the change if applicable.  ## Checklist - [ ] I have read and understood the [contribution guidelines](https://isaac-sim.github.io/IsaacLab/main/source/refs/contributing.html) - [ ] I have run the [`pre-commit` checks](https://pre-commit.com/) with `./isaaclab.sh --format` - [ ] I have made corresponding changes to the documentation - [ ] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works - [ ] I have updated the changelog and the corresponding version in the extension's `config/extension.toml` file - [ ] I have added my name to the `CONTRIBUTORS.md` or my name already exists there
