unreal.PCGAttributeReduceSettings

class unreal.PCGAttributeReduceSettings(outer: Object | None = None, name: Name | str = 'None')

Bases: PCGSettings

Take all the entries/points from the input and perform a reduce operation on the given attribute/property and output the result into a ParamData. Note: Special case for average on Quaternion since they are not trivially averageable. We have a simplistic approximation that would be accurate only if the quaternions are close to each other. The accurate version of the average is using eigenvectors/eigenvalues which is way more complicated and computationally expensive. Quaternion will also be normatilzed at the end. Beware if you are using this average.

  • merge_output_attributes (bool): [Read-Write] Option to merge all results into a single attribute set with multiple entries, instead of multiple attribute sets with a single value in them.
