Hello, I’m a newbie reading source code of StaticMeshOperations.cpp, and I notice that in function
FStaticMeshOperations::ApplyTransform
It applys same matrix on normal and tangent vectors, which is the inverse transpose of transfom matrix. But after searching online for a while, all people say that only normal should be transformed like this in case of non-uniform scale, tangent should use the original matrix,
So which one is the correct way to transform tangents?
