Syntax

TArray< FGeometryCollectionSection > BuildMeshSections
(
    const TArray< FIntVector > & Indices,
    TArray< int32 > BaseMeshOriginalIndicesIndex,
    TArray< FIntVector > & RetIndices
) const

Remarks

Builds mesh sections for a given index buffer that could be a subset. Currently, this call assumes that the indices are ordered by MaterialID #todo(dmp): Refactor this and ReindexMaterials to share code
