weightRemapper Node
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
More Compact Normalized Control (Maya 2020)
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
Better Binding On The TranslateUVN Deformer
One of the known issues for the translateUVN deformer (and all the other custom deformers I had made that used bindData) is that they created bind data for every component on the shape even if that component was not included in the deformerSet. I set it up this way for two reasons: So that if a user added a new component to the deformer it would already have bind data and they wouldn't need to rebind it. Because I didn't know how to get the contents of the deformerSet in a co
Infinite UVN Range + Infinite Binding
The previous method of binding components to a nurbs surface was to find the closest point on the nurbs surface, and then create a matrix based on the position, normals, and tangents of that point. That matrix, plus the U and V coordinates of the point on the surface were recorded as the bind data for that component. This worked perfectly fine for that iteration for that iteration of the UVN deformer but since points can now slide beyond the surface an unaccounted for fringe
