Re: StudioMM
I have the same situation as yours. After exploring the CC4 within these several days, I find :
1) There is a new Plugins of Blender Auto for CC4 :
Blender Auto Setup (reallusion.com)2) CC4 > Blender > CC4 ... is the most convenient method to create character. For Cartoon, consider to purchase "Cartoon Design Content ... etc" and modify the characters with CC4 and Blender.
3) Blender > CC4 : you can import your character as Humanoid. But it is horrible if we use ARP(auto rip pro). The bones becomes mess and time consuming to re-match in CC4.
Instead, we should use meta rig - Rigify in Blender but you know the weights ...... and we have to refine the character again .....
4) "Greyed out" problem occurred due to missing .fbxkey file which CC4 produces after exporting .fbx file. Thus, CC4 > Blender > CC4 ... / Humanoid ... up to you ..
