Feature

Completed (record path; image quality stays TODO(UNVERIFIED) unless a capture is listed in PLAN):

• ThinGBuffer (Crytek A/B + GBufferC flags/SSS)
• TemporalAA (jitter-free motion, direct-texel history)
• RenderGraph (custom RGBuilder + async compute hooks)
• Screen-space GI / reflection (RayMarch → Spatial → Temporal → Bilateral + Composite)
• Ground-truth ambient occlusion (Trace → SpatialX/Y → Temporal → Upsample)
• Atmosphere LUT + IBL (Profile-only; Shared / View / IBL caches)
• Z-Binning tile / z-bin light lists
• Volumetric fog and cloud (after T0 depth) + FogComposite
• Translucent T0 / T1 refraction / T2
• Exposure / Bloom / CombineLUT / Vignette / FilmGrain / OutputTransform
• Instanced terrain / runtime virtual texture / foliage systems (separate from MeshScene)
• Mesh Drawing Pipeline — MeshScene SoA + RDG RGDrawListRef + CPU/GPU backends (per-payload indirect, Auto fallback); Motion / CascadeShadow / LocalShadow (Spot + Point 6-face) MeshDraw; instance-indexed GPU cull (compact → transform); exclusive TransformId 1:1 ownership; shared renderingLayer (ERenderingLayer : byte flags); shadow MeshDraw uses light.cullingMask + shadowLayer; no HZB / GPU radix sort / full GPU LOD in this closed slice

Out of this delivery:

• Hardware RT (RTAO/RTGI files stay; no RG pass)
• Baked GI
• Depth of field
• Super-resolution expansion
• XR
• MSAA
• Dynamic resolution

Mesh Drawing Pipeline (quick start)

1. Add Mesh Component to renderable objects (Infinity path). Set renderingLayer as flags (ERenderingLayer : byte, default LightLayerDefault) — not an int layer index. Each instance owns exactly one TransformId (no shared transforms).
2. On the pipeline asset, assign Mesh Draw Pipeline CS (Compute_MeshDrawPipeline.compute) to enable Auto GPU-indirect when supported.
3. Materials should provide Infinity pass tags and, for the instanced path, bind transformBuffer / previousTransformBuffer / instanceIndexBuffer / instanceIndexOffset (see InfinityLit-Instanced.shader).
4. LocalShadow / CascadeShadow MeshDraw uses the light’s Unity cullingMask plus LightComponent.shadowLayer for Infinity casters; Unity MeshRenderers still go through RendererList. Spot or Point lights with shadows enabled are required for LocalShadow.
5. Run EditMode tests under Tests/Editor.

Invariant: one logical instance → one exclusive transform record (MatrixDuplicateRatio == 1).
