Unlike in a skinCluster-based system if you use a translateUVN deformer you'll need to define which maps are left/right pairs for each other. To do this we just need: An inputWeightList attribute An outputWeightList attribute (these attributes need to have useArrayDataBuilder set to true so that they update properly) A the left and right vertex pairing for each shape An internal system for pairing the input and output shape plugs. Those first two requirements can be done with

I had a post on this blog from around 6 months ago about how to create a vanilla version of a normalized control because the custom transform node method I was pursuing ended up being more complicated to implement because of manipulator issues. I finally toyed around with the parentOffsetMatrix attribute that was added in Maya 2020 and it's great. The whole system can be compressed from 4 transforms nodes (zero, offset, normal, control) to a single control node that does it a
