Hey BA,
Is there a way currently in Blender 2.83 or via an add-on to bake the results of Smooth Corrective (Delta Mush) to the weights? This is a technique commonly used in Maya to quickly weight characters with minimal weight painting. Once happy with the weights, users can either use the built-in “Bake Deformer Tool” or a script called “Deformation Learning Solver” to bake the results to the objects weights for export (Unreal 4 / Unity / fbx). Here’s a video that shows the process for those who are curious:
Thanks!
