Goo Blender 5.2.0_2026.9.5

Fixed a bug related to light groups. Now, as long as a shader-info node is used in the material, the light group will be automatically enabled; materials that don’t use a shader-info node won’t be affected by the light group.

修复了有关灯光组的bug。现在只要在材质当中使用了shader-info节点，就可自动启用灯光组；未使用shader-info节点的材质则不受灯光组影响。

Goo Engine 5.2 Port

This repository is an unofficial port of Goo Engine to Blender 5.2 and EEVEE-Next.

Goo Engine is an NPR (non-photorealistic / toon rendering) focused fork of Blender
created and maintained by DillonGoo Studios. The original project is based on
Blender 4.4.x and the legacy EEVEE render engine:

• Original repository: https://github.com/dillongoostudios/goo-engine
• Original authors: DillonGoo Studios and the Goo Engine contributors
• Studio website: https://www.dillongoo.com

This port takes the Goo Engine v4.4-release feature set and re-implements it on top of
official Blender 5.2.0 (EEVEE-Next render engine, BSL shader pipeline). This repository
is not affiliated with the Blender Foundation or DillonGoo Studios. All code remains
under the GNU General Public License.

What Was Ported and How

• 13 Goo shader nodes, with their GLSL re-implemented for the EEVEE-Next BSL pipeline:
  Shader Info, Screenspace Info, SDF Primitive, SDF Op, SDF Vector Op, SDF Noise,
  Set Depth, Curvature, Light Info, Hexagon Texture, Twirl, Water Ripples,
  and OKLab Color Ramp.
• Set Depth rewritten for the reverse-Z depth convention of EEVEE-Next.
• Curvature ported with the original 8-direction sampling algorithm, and screen-space
  depth sampling aligned with Goo's output.
• OKLab Color Ramp aligned with Goo's render path (easing behavior and linear output).
• Light Groups management UI (scripts/startup/goo_engine_light_groups.py) together
  with the Light DNA/RNA extensions; shader Add menu regrouped into Goo categories.
• Legacy material semantics restored through file versioning:
  • MA_LEGACY_OPAQUE (legacy blend_method == Opaque) is tagged at load time, gated by
    "material node tree uses a Goo node OR file version < 4.2" (file subversion 502.47,
    with clear-and-recompute). This keeps Goo scenes force-opaque where intended while
    not breaking transparent materials in files saved by official Blender (whose legacy
    DNA fields are zero-filled and would otherwise be misread).
  • Legacy Shadow Mode = None (blend_shadow) is honored at render time so shadow
    proxy workflows from Goo scenes keep working.
  • Files older than Blender 2.80 (whose SDNA lacks Material::blend_shadow) are
    backfilled to the solid default via an SDNA member-existence check, preventing
    the zero-filled value from silently disabling all shadow casting.
• Highlight (HL) fix: purely geometric highlights were being culled by the light
  attenuation gate and light culling; fixed with a bridged gate.
• Forward pipeline light cap raised to 512 visible lights per fragment.
• Contact shadows bridged to EEVEE-Next equivalents; legacy Bloom migrated to Glare
  through versioning; a file browser crash fixed.
• Build configuration: WITH_INTERNATIONAL, WITH_INPUT_IME and WITH_BULLET
  enabled (the lite profile shipped with these off, which broke language switching,
  IME input and rigid body physics).

Known Boundaries and Their Handling

• Visible light count per fragment: 128/256/512 verified working; 1024 fails on the
  tested hardware. The cap is set to 512.
• Light resource access in material nodes: EEVEE-Next does not expose light data to
  material shaders in every pass; the affected Goo nodes degrade gracefully per pass.
• BSL limitation: conditional attributes/parameters (#if) are not supported inside
  fragment signatures by the shader tooling; code is organized around unconditional
  signatures.
• blend_shadow zero-value ambiguity (residual): a full fix via a dedicated
  MA_LEGACY_NO_SHADOW flag (file-level Goo fingerprint at load, flag read at render)
  has been designed but not implemented. Known corner case: appending a shadow-None
  material that itself contains no Goo nodes into a scene without any Goo nodes will
  make it cast shadows.
• RNA re-entrancy deadlock: property_pointer_get (rna_access.cc) can self-deadlock
  on a non-recursive mutex when an ID-type IDProperty group is overwritten with a flat
  value and later resolved. The engine defect is documented; callers must write geometry
  nodes modifier inputs as inputs[identifier]["value"] = value (never overwrite the
  {value, type} group), which avoids the code path entirely.
• File subversions 502.45-48 are used by this fork. If a future official 5.2.x LTS
  release uses the same subversion numbers for its own versioning, files saved by this
  fork could skip those official versioning blocks.
