Context: - Nanite meshes distance fields are generated using the original mesh data instead of the coarse representation generated by Nanite, however that code path was not checking section data such as blend mode, two sided, etc. Fix: - Modified FStaticMeshBuilder::BuildMeshVertexPositions(...) to also output a FStaticMeshSectionArray. - Updated MeshRepresentation::SetupEmbreeScene(...) to check section flags when using SourceMeshData.IsValid() code path. #prelight #rb Krzysztof.Narkowicz [CL 26160411 by tiago costa in ue5-main branch]
