- Normal render target (R16G16B16A16_SNORM) as MRT SV_TARGET1 in all 3 pixel shaders (voxelPS, voxelTopingPS, voxelSmoothPS) for future RT shadow/AO - BLAS extraction compute shader (voxelBLASExtractCS.hlsl): converts PackedQuad StructuredBuffer to float3 position buffer for DXR BLAS input - Blocky BLAS: single BLAS from all GPU-meshed quads (~1.5M triangles) - Smooth BLAS: single BLAS from smooth vertex buffer directly - TLAS: 2 instances (blocky + smooth), identity transforms, CreateBuffer2 with callback to avoid UpdateBuffer on RAY_TRACING flagged buffers - Fix: Wicked always accesses index_buffer in CreateRaytracingAccelerationStructure via to_internal() even for non-indexed geometry — provide dummy valid buffer
