Dang, I was hoping you had a magic bullet. Right now my process is basically getting the initial skinning onto a Mixamo rig with just the base mesh, then copying that to other LODs, and then renaming and adding bones until it’s the same as the Epic skeleton.
Unfortunately Mixamo’s skinning leaves something to be desired, and Maya’s skinning tools are terrible (at least I have a lot of problems with getting smooth gradients, and painting across seams).
Speaking of which, do you have any trips for painting weights across seams? Because it seems to work pretty poorly. I tried to find plugins or scripts to help but most don’t seem to affect the ability to e.g., smooth across a seam in the mesh.
