Hey guys, I want to write a plug-in that provides feedback on a couple of properties while creating blendshapes. (such as surface compression/tension, or even just "amount moved from base shape"). Ive written nodes in the past that affect vertex color and pass it on the output mesh, but this case seems a bit different in that one of the input attributes is the vertex positions of the final mesh (which is being edited).
I'd love any guidance on best approach here! Im looking for examples for how tools like the softmod seem to draw colors on the mesh without creating a colorset - any suggestions on where I should be looking would be appreciated!
Worst case scenario I suppose I'd fall back to a toggle-like behaviour where the artist can use a hotkey to display this custom vertex colorset, then switch back to modelling.
