Holds Translucency / Luminosity / Diffuse / SurfOpacity / NeedsUvRepeat / DisableFog keyed by (gfxObjId, surfaceIdx). Populated at extraction time, queried by the draw dispatcher. ConcurrentDictionary because mesh extraction happens on background workers. No fork patches required — keeps WB's MeshBatchData pristine. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
