Yes. It all boils down to morph delta values.

To explain why there is unified/non-unified loading:

On body part welds, one has two morph delta values s for the same vertex (sad but true). Only one of them moves the vertex - the other one is hidden, and only has effect on the normal (and therefore the shading). Unified means that both values will be set identical - this is what most programs do, and that mostly works good.

My personal experience was that non-uniform deltas can make results with a better shading, especially if the joint is highly disrupted. But this is not always true, this is why both modes are included.

I tried for a while to use the hidden morph delta to produce normals that are perfectly smooth, but this seemed to be not possible or just outside my capabilities. The modification of a vertex morph delta modifies not only the normal of just this vertex, but also of the vertices that are around it, which makes things more difficult.

I'm really looking forward to see the JCM's you made!!
