void RecomputeNormalsAndTangents

bool bMakeSharpEdges,
float SharpAngleDegrees,
FGeometryCollection & Collection,

Remarks
Recompute normals and tangents of selected geometry, optionally restricted to faces with odd or given material IDs (i.e. to target internal faces)
Parameters
| Name | 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 |
