Hi. I am using cc4 and iclone8. I import modeled files from sketchfab site and do rigging work in cc4. But the most difficult thing is face rigging. Then I found a site for AI face auto rigging. It's a paid program, so you can't use it, but you can get auto converted sample files. I would love to see this feature added to CC4, or released as a plugin.
1. Add CC4 native functionality or create a plugin
2. research where AI technology can be applied to cc4 or icone8
