Here is the FBX data that integrates the human body, hair, and clothing.
As we can see, when I move her, her hair and clothing penetrate her body.

Regarding how to prevent penetration, what part of online manuals should I refer to?
If anyone knows about it, please let me know.
Actually, I asked the same question in the past and received an answer, but it did not lead to a solution.

The point to note here is that When creating a character with CC, hair, clothing, and the human body are combined as separate iprops,
but I have hair, clothing, and the human body in one piece of data.
Do I need to prepare ihair, icloth, and ccbody respectively in order to prevent penetration?
