Months ago I make a question about how to modeling these kind of characters and I have a good answer from Alex in this post
http://wiki.polycount.com/wiki/SkankerzeroModularCharacterSystem, but now I have a big question ¿How to rigging and animating a 3d modular character?. I could see some information, but I can't understand a confuse pipeline.
I read something about rigging a single mesh, and after that cut every part of the body with the skeleton included.
In other website I read about paint weights separately of every body part and then combine the body.
Is necesary weld the vertexs before rigging or only combine and after that make the rigging?
Pls I need answers :'C
