Parameters

Parameter	Description
bOnlyTangents	If true, leave normals unchanged and only recompute tangent&bitangent vectors
bMakeSharpEdges	If true, recompute the normal topology to split normals at 'sharp' edges
SharpAngleDegrees	If bMakeSharpEdges, edges w/ adjacent triangle normals deviating by more than this threshold will be sharp edges (w/ split normals)
Collection	The Geometry Collection to be updated
TransformIndices	Which transform groups on the Geometry Collection to be updated. If empty, all groups are updated.
bOnlyOddMaterials	If true, restrict recomputation to odd-numbered material IDs
WhichMaterials	If non-empty, restrict recomputation to only the listed material IDs
