Hi primorge

I thought about doing this, but for example some morphs will not work.

For example, the original character of the V4 has a ass horrible when she is sitting.
Some third-party morphs correct this error.

Use the procedure you described does not solve the problem, her ass is still horrible with or without pants.

That is why I asked the question

Anyway your idea I'll use it for sure.

Other way ?
