TMeshTangents::ComputePerTriangleTangents

Calculate per-triangle tangent spaces based on the given per-triangle normal and UV overlays.

Windows

MacOS

Linux

Syntax

void ComputePerTriangleTangents
(
const FDynamicMeshNormalOverlay * NormalOverlay,
const FDynamicMeshUVOverlay * UVOverlay
)

Remarks

Calculate per-triangle tangent spaces based on the given per-triangle normal and UV overlays. In this mode there is no averaging of tangents across triangles. So if we have N triangles in the mesh, then 3*N tangents are generated. These tangents are computed in parallel.
