• Runtime build hash: 0554f88d0014
• GitHub continuation snapshot: 427d6476
• Release ZIP SHA256: CAEF0F41BDCEAEAB50BD4E0944D151B61622DBF23515F2B885851B8739924681

Panel Identifier Hotfix

• Registers the Output Properties Overscan panel as
  RENDER_PT_exr_overscan instead of the generic RENDER_PT_overscan.
• Prevents third-party add-ons that use the generic identifier from replacing
  the Industrial CG Platform panel.
• Adds a runtime regression assertion that requires the product-specific panel
  identifier and rejects the old generic identifier.
• Keeps the retained release identity synchronized as
  Blender 5.2.0-2026-06-18 Industrial CG Platform.

Highlights

• Publishes the clean Industrial CG Platform feature stack while preserving
  the curated GitHub continuation-repository model.
• Includes Shadow Color, Deep EXR and GPU compositor support, Lightgroup lobe
  passes, the BQt ViewLayer Manager, Industrial CG Platform branding, and the
  accepted EXR Overscan workflow.
• Passes the installed-release integrity gate, including bundled BQt runtime
  and ViewLayer Manager import checks.
• Passes the complete EXR Overscan offline regression suite and both GUI popup
  states with panel_idname recorded as RENDER_PT_exr_overscan.

Publication Notes

• This asset replaces the earlier package under the existing
  industrial-cg-platform-5.2.0-2026-06-18 release identity.
• The GitHub repository is a curated continuation repository. Its snapshot
  commit intentionally differs from the local full-history source hash.
• The previous local release root, ZIP, and notes are preserved under
  .agent/archive/release-staging/2026-06-18_pre_panel_id_fix_formal_release.

Release SHA256: ABF163964C0DDE4754EC1E03BE28B962FD0520892CC20489271E7B1286D82B87

Highlights:

• includes the validated EXR overscan redesign-v2 stack from b1178a6f684, 3cb97d34346, and 51091989dec, covering offline EXR overscan output, compositor/File Output window preservation, render-region gating, Output-panel overscan controls, viewport safety-frame guidance, and the OptiX cache-path policy
• keeps the shipped Deep EXR runtime kernel-header packaging follow-up from e3e08831df1, so fallback Cycles kernel compilation does not lose deep_write.h in the installed runtime
• keeps the Deep EXR output UI cleanup from ee70775a762, removing the redundant standalone Deep EXR panel while preserving the existing file-output workflow
• carries the current Industrial CG Platform branded runtime and passes the full self-contained feature suite, including HADY GUI Cycles on both CPU and OPTIX plus the old-scene compositor Deep EXR semantic gate

Highlights:

• includes the BQt startup-prewarm integration from 0bff869674a so the bundled ViewLayer Manager preloads its Qt runtime during Windows GUI startup instead of paying the full cold-start cost on first open
• includes the .blend launch re-arm fix from c598559a0b5, ensuring the prewarm timer survives file-load startup and keeps direct project-launch sessions on the warmed path
• keeps the deeper bundled-runtime integrity checks in scripts\modules\blender_vfx_qt\__init__.py, so stale partial bqt or PySide6 imports are cleared before recovery enable attempts
• rebuilds the branded package through the validated clean Ninja release workflow with the release date and runtime version string aligned to 2026-05-27

Binary build source commit: bede48d67c1e
GitHub continuation snapshot commit: d915fa5

Release artifact:

• industrial-cg-platform-5.2.0-2026-05-19.zip
• SHA256: 519D82A17F18C2F4B2F0D36C512BA6CAFFB209D70D0EBA9CC06AA8152C3D421F

Notes:

• This GitHub branch is a continuation snapshot for ongoing development, not a full historical mirror of the local source repo.
• The continuation snapshot intentionally omits heavyweight upstream test fixture payloads under tests/files/ that are not locally available on this workstation.
• The continuation snapshot also omits two macOS-only upstream LFS resources that were not locally available during publication: release/darwin/Blender.app/Contents/Resources/Assets.car and release/darwin/Blender.app/Contents/Resources/blender_icon_legacy.icns.
• The branded Windows runtime and splash used for this release were verified locally before packaging.

blender-vfx-5.2-2026-05-18

Included

• BQt-based ViewLayer Manager bundled into the Windows zip release.
• Shared Qt runtime bundled as a system extension, including the staged bqt, PySide6,
  QtPy, and related wheel payloads needed by the manager.
• ViewLayer Manager workflow includes:
  • top-right ViewLayer Manager launcher in Blender
  • current-scene ViewLayer lifecycle controls
  • pass controls for Eevee and Cycles
  • Cryptomatte
  • Shader AOV
  • Light Groups
  • Cycles light-pass AOVs
  • Deep
  • pass presets
  • Chinese and French manager translations
• Bundled system-extension repo layout fix, so the packaged runtime now discovers:
  • blender_vfx_qt_runtime
  • blender_vfx_viewlayer_manager
    from the installed System repository without manual directory repair.

Validation

• Installed release reports:
  • build hash: af21acdd037d
  • build branch: vfx-rendering-branch-github
• Installed package command checks pass:
  • --factory-startup --command help
• Installed package system-extension discovery checks pass:
  • local System repo scan includes blender_vfx_qt_runtime
  • local System repo scan includes blender_vfx_viewlayer_manager
  • packaged runtime imports:
    • bl_ext.system.blender_vfx_qt_runtime
    • bl_ext.system.blender_vfx_viewlayer_manager
• Installed package contains no broken nested extensions/system/system/<extension> runtime path.

Notes

• The published branch head for the packaged extension-layout fix is:
  b69596cd20bf10812a84fccc34ae9f4f1e5978df
• The executable build hash remains af21acdd037d because the follow-up fix only changed the
  bundled extension payload layout, not the compiled Blender binary itself.

blender-vfx-5.2-2026-05-11

blender-vfx-5.2-2026-05-11

Included

• Env lightgroup lobe reconstruction fixes for world/background contributions, including the
  follow-up for view layers that disable both Background and Emission passes.
• Ordinary finite-light lamp-hit split-lobe fix, so area/finite lightgroups such as production
  fill03 now reconstruct back to Combined instead of losing energy in the split-lobe family.
• Built from the local public-release branch head 3d76509a3fc on
  vfx-rendering-branch-github.

Validation

• Installed release reports:
  • build hash: 3d76509a3fce
  • build branch: vfx-rendering-branch-github
• Installed package command checks pass:
  • --factory-startup --command help
  • --factory-startup --command maketx --help
• Installed package contains no Git LFS pointer stubs.

• User-profile startup may still log unrelated third-party add-on import/runtime errors, but they
  did not block package validation or background rendering in the release test run.

blender-vfx-5.2-2026-04-20

blender-vfx-5.2-2026-04-20

Public GitHub release package for the Cycles lightgroup split-pass readback fix.

Fixes

• Fixes lightgroup lobe split-pass output when only Direct and/or Indirect passes are enabled.
• Preserves named lightgroup/lobe pass identity during PathTraceTile readback.
• Avoids the direct/indirect-only empty-output and cross-pass overwrite regression.
• Keeps the validated source patch minimal and limited to the 5-file Cycles readback fix set.

Package Truth

• Build hash: 1529cdc8582b
• Build branch: vfx-rendering-branch-github
• Package folder: E:\blender_modify\release\blender-vfx-5.2-2026-04-20
• Zip: E:\blender_modify\release\blender-vfx-5.2-2026-04-20.zip

Validation

• CUDA direct_indirect_only: passed
• OPTIX direct_indirect_only: passed
• CUDA combined_plus_split with aggregate balance checks: passed
• OPTIX combined_plus_split with aggregate balance checks: passed
• maketx command help works in the installed package
• Installed package contains no Git LFS pointer stubs
• Installed package contains the full release CUDA architecture matrix plus OptiX kernels
• Packaged .pdb files were archived outside the release folder before zipping

Notes

• Per-lightgroup aggregate direct/indirect balance for env and key is gating.
• Global raw beauty comparisons remain diagnostic/report-only.
• RGBA_emissive remains combined-only and is included only in the global beauty diagnostic path.
• The earlier full-history 2026-04-20 candidate was archived after GitHub push attempts stalled on remote pack/index processing.

blender-vfx-5.2-2026-04-14

Release Notes

• Fix Deep EXR compositor GPU compatibility so scene.render.compositor_device='GPU' can write Deep EXR file outputs without forcing the whole compositor back to CPU.
• Keep the rest of the compositor GPU scheduling path active for non-Deep-EXR nodes instead of disabling GPU execution broadly.
• Continue to ship the current VFX rendering branch feature set, including Deep EXR, Shadow Color, Lightgroup Lobe Passes, and the recent upstream Blender 5.2 texture-cache command workflow.
