Hi mrnitro
Looking forward to see some results with your method, we are always happy to see new ways people using Ziva
Some suggestions that may help you:
1) If you are doing cartoony type character then you can try "marshmallow" rig, here is an example
2) If you are going to combine bones and muscles in one mesh then you should not use it as collision mesh, it can cause some collision issues but it's fine to use it for attachments
Hope this helps ! = )
