Detailed Description

Defined a named region on a mesh that will have associated triangles and bones for fast sampling at each enabled LOD.

Constructor & Destructor Documentation

◆ FSkeletalMeshSamplingRegion()

FSkeletalMeshSamplingRegion::FSkeletalMeshSamplingRegion ( )

Member Function Documentation

◆ GetFilteredBones()

void FSkeletalMeshSamplingRegion::GetFilteredBones ( struct FReferenceSkeleton &  RefSkel,
TArray< int32 > &  OutIncludedBoneIndices,
TArray< int32 > &  OutExcludedBoneIndices 
)

Directly included vertices from a future painting tool. Directly included bones from a future painting tool.

◆ IsMaterialAllowed()

bool FSkeletalMeshSamplingRegion::IsMaterialAllowed ( FName  MaterialName)

Member Data Documentation

◆ BoneFilters

TArray<FSkeletalMeshSamplingRegionBoneFilter> FSkeletalMeshSamplingRegion::BoneFilters

Filters to determine which triangles and bones to include in this region based on bone.

◆ bSupportUniformlyDistributedSampling

uint32 FSkeletalMeshSamplingRegion::bSupportUniformlyDistributedSampling

Mesh supports uniformly distributed sampling in constant time. Memory cost is 8 bytes per triangle.

◆ LODIndex

int32 FSkeletalMeshSamplingRegion::LODIndex

The LOD of the mesh that this region applies to.

◆ MaterialFilters

TArray<FSkeletalMeshSamplingRegionMaterialFilter> FSkeletalMeshSamplingRegion::MaterialFilters

Filters to determine which triangles to include in this region based on material.

◆ Name

FName FSkeletalMeshSamplingRegion::Name

Name of this region that users will reference.
