RootToUniqueTriangleIndexBuffer

Triangle on which a root is attached When the projection is done with source to target mesh transfer, the projection indices does not match.

Unreal Engine C++ API Reference > Plugins > HairStrandsCore > FHairStrandsRootData > FMeshProjectionLOD

Syntax

TArray< FHairStrandsRootToUniqueTriangleIndexFormat::Type > RootToUniqueTriangleIndexBuffer

Remarks

Triangle on which a root is attached When the projection is done with source to target mesh transfer, the projection indices does not match. In this case we need to separate index computation. The barycentric coords remain the same however.
