Description
Append normals from one attribute overlay to another. Assumes that AppendMesh has already been appended to Mesh. Note that this function has no dependency on .Mesh, it could be static

Parameters
| Name | Remarks |
|---|---|
| AppendMesh | mesh that owns FromNormals attribute overlay |
| FromNormals | Normals overlay we want to append from (owned by AppendMesh) |
| ToNormals | Normals overlay we want to append to (owned by Mesh) |
| VertexMap | map from AppendMesh vertex IDs to vertex IDs applicable to ToNormals (ie of .Mesh) |
| TriangleMap | map from AppendMesh triangle IDs to triangle IDs applicable to ToNormals (ie of .Mesh) |
| NormalTransform | optional transformation function applied to mesh normals |
| NormalMapOut | Mapping from element IDs of FromNormals to new element IDs in ToNormals |
