there’s at least a rudimentary
Help/Addon at least you can create groups which makes the whole thing clearer.
but same with the vertexgroups,
also the rigging/weightpainting becomes very confusing,
if you have several deformation models
(Rig-bone-vertex together with individual weightmapsgroups for e.g. smoothing certainregions) the chaos is perfect.
Here it would be nice if you could structure different vertexgroups.
