Member Data Documentation

BaseIndex

uint32 FSkelMeshRenderSection::BaseIndex

The offset of this section's indices in the LOD's index buffer.

BaseVertexIndex

uint32 FSkelMeshRenderSection::BaseVertexIndex

The offset into the LOD's vertex buffer of this section's vertices.

bCastShadow

bool FSkelMeshRenderSection::bCastShadow

This section will cast shadow

bDisabled

bool FSkelMeshRenderSection::bDisabled

Disabled sections will not be collected when rendering, controlled from the source section in the skeletal mesh asset

BoneMap

TArray<FBoneIndexType> FSkelMeshRenderSection::BoneMap

The bones which are used by the vertices of this section. Indices of bones in the USkeletalMesh::RefSkeleton array

bRecomputeTangent

bool FSkelMeshRenderSection::bRecomputeTangent

This section will recompute tangent in runtime

bVisibleInRayTracing

bool FSkelMeshRenderSection::bVisibleInRayTracing

If true, this section will be visible in ray tracing effects. Turning this off will remove it from ray traced reflections, shadows, etc.

ClothingData

FClothingSectionData FSkelMeshRenderSection::ClothingData

Clothing data for this section, clothing is only present if ClothingData.IsValid() returns true

ClothMappingData_DEPRECATED

TArray<FMeshToMeshVertData> FSkelMeshRenderSection::ClothMappingData_DEPRECATED

The extra vertex data for mapping to an APEX clothing simulation mesh.

ClothMappingDataLODs

TArray<TArray<FMeshToMeshVertData> > FSkelMeshRenderSection::ClothMappingDataLODs

The cloth deformer mapping data to each of the required cloth LOD. Raytracing may require a different deformer LOD to the one being simulated/rendered. The outer array index represents the LOD bias. The inner array indexes the vertex data. If this LODModel is LOD3, ClothMappingDataLODs[1] will point to defomer data using LOD2, and ClothMappingDataLODs[2] will point to defomer data that are using cloth LOD1, ...etc. ClothMappingDataLODs[0] always point to defomer data of the same cloth LOD, this is convenient for cases where the cloth LOD bias is not known or required.

CorrespondClothAssetIndex

int16 FSkelMeshRenderSection::CorrespondClothAssetIndex

DuplicatedVerticesBuffer

FDuplicatedVerticesBuffer FSkelMeshRenderSection::DuplicatedVerticesBuffer

Index Buffer containting all duplicated vertices in the section and a buffer containing which indices into the index buffer are relevant per vertex

MaterialIndex

uint16 FSkelMeshRenderSection::MaterialIndex

Material (texture) used for this section.

MaxBoneInfluences

int32 FSkelMeshRenderSection::MaxBoneInfluences

max # of bones used to skin the vertices in this section

NumTriangles

uint32 FSkelMeshRenderSection::NumTriangles

The number of triangles in this section.

NumVertices

uint32 FSkelMeshRenderSection::NumVertices

The number of vertices in this section.

RecomputeTangentsVertexMaskChannel

ESkinVertexColorChannel FSkelMeshRenderSection::RecomputeTangentsVertexMaskChannel

Which channel for masking the recompute tangents
