Constructor.

Parameters:

  • path (str) – Prim path.

  • new_transform_matrix (Gf.Matrix4d) – New local transform matrix.

  • old_transform_matrix (Gf.Matrix4d, optional) – Old local transform matrix that is used for undo. If it’s not given, it’s the current local transform matrix when this command is instantiated. Default is None.

  • time_code (Usd.TimeCode) – The timecode to change. Default is Usd.TimeCode.Default().

  • had_transform_at_key (bool) – If the local transform is set already before this command. This is used for undo to decide if it needs to clear the new value. Default is False.

  • usd_context_name (str) – The UsdContext to operate. Default is empty, which means the default UsdContext is used.
