Strange skeleton during sex animations

[UglyManG]

Alright so I'm using the following mods related to appearance/animations/etc...

 

XPMS Extended, FNIS, HDT, SexLab 1.57, ZazAnimation, CBBEv3

 

And I'm getting a weird belly effect during sex animations

Graphic nudity in the spoiler.

 

 

 

The effect only occurs during sex animations. I'm not sure where I've made a mistake but if someone could possibly help me figure it out or point me to a fix if this is a known issue I'd appreciate it.

That is caused by a incompatible skeleton/incorrect skeleton.

So i should redownload and reinstall the XPMS?

Yes re-install whatever skeleton you were using and watch what mods you install so that nothing gets overwritten as some mods might contain their own skeleton in it and it might overwrite your exististing skeleton if you are not watching you see stretching like this in oblivion as well when a skeleton you are using gets overwritten by another mod that has a skeleton in it. I usually unzip mods and check them out to see what is all in the rar and load it up into nifskope so that I can catch some of the mistakes before putting it into game.
