void SetGeneralTubeUVs (     const TArray < int > & Triangles,     const TArray < int > & VertexIDs1,     const TArray < int > & MatchedIndices1,     const TArray < int > & VertexIDs2,     const TArray < int > & MatchedIndices2,     const TArray < float > & UValues,     const FVector3f & VDir,     float UVScaleFactor,     const FVector2f & UVTranslation,     int UVLayerIndex )

Remarks

For triangles connecting loops of corresponded vertices, set UVs in a cylindrical pattern so that the U coordinate starts at 0 for the first corresponded pair of vertices, and cycles around to 1 Assumes Triangles array stores indices of triangles in progressively filling the tube, starting with VertexIDs*[0]. (This is used to set the UVs correctly at the seam joining the start & end of the loop)
