I load the cloth, conform it and all is well except that there are morphs missing and poke through appears.

So I add then morphs which were in the figure to the clothing. All seems well at that point. Then I pose the figure, and I get what you see in the attached image

This is a cloth from the marketplace rigged for that figure. So no fitting room involved.

Doing the same procedere with a v4 works fine

However...

If I pose the figure first and then add the morphs I do not get the problem.

So who or what is the cause of the problem?
