occurrences (OccurrenceList) : Occurrences of part to process sourceUVChannel (Int) : UV Channel to normalize destinationUVChannel (Int) [optional] : UV channel to store the normalized UV (if -1, sourceUVChannel will be replaced) uniform (Boolean) [optional] : If true, the scale will be uniform. Else UV can be deformed with a non-uniform scale sharedUVSpace (Boolean) [optional] : If true, all parts will be processed as if they were merged to avoid overlapping of their UV coordinates ignoreNullIslands (Boolean) [optional] : If true, islands with null height and width will be ignored and their UV coordinates will be set to [0,0] (Slower if enabled)
