As far as i understand, you usually create a uvSet and then call assignUVs to map triangle corners to uvIDs.
But uvSets are exposed as a plug, too. When I use the uvSet plug to generate UVs in a node, how do i trigger the assignUVs function of the shape object to (re)assign the uvSet, when the uvSet output from the uvGenerator node changed?
