Each coloured segment is a single bone
EDIT: Just to clarify any confusion, this is NOT Pose Sculpting. That is a separate project. See this instead for the latest updates.
So far, I've mostly been cleaning up the initial patch by Jose Molina, and trying to figure out what it does, how, why, and also trying to identify and fix bugs. For example:
Pinguino (Caminandes 3) is not looking too flash either!
I found yesterday that apparently it doesn't work so great with old Blenrig files. I'll have to look into why it's failing, but it'll either be the lack of version patching, or something more sinister :/
There's also a bug in how there are gaps between the bone segments (as shown in the viewport). Attempts to fix this so far have resulted in the deforms going crazy instead... so, maybe it's something we'll have to live with - it could well be a good way to indicate the different ways that these work?
Currently I'm only tinkering with this in a local branch, but I'll push the branch to the main repo soon when I figure out what's going on with these bugs. Until then, hope you enjoyed this little update!
