Hi everyone!
I exported CC3+ avatar with bones from CC4. After, i changed his head for custom in 3ds max. The bones were preserved.
After, i import my model as humanoid avatar.
Did characterization:

The result is a working animation. Poses can be changed:

But if I try to add clothes to the avatar, this error appears:

Attempt to apply the body part has failed due to incompatibility with the current character. Body parts of CC3+ Character and Humanoid characters can not be shared or exchanged.
How to fix that issue? And add clothes to custom avatar?
