Help with weird ass deformation (screenshots inside)

[Bayman]

Don't know what causes this ugly edge. I think it came from the TBBP bones I added to the 7B Bombshell (more bounce) body? I also use the "All in one_Breast physics-Breast collision-HDT Havok Object".

 

When I change back to the original 7B Bombshell files (femalebody_0.nif, femalebody_1.nif). The butt is round and looks really good. I know, you guys are using butt physics too, and I'm sure it's just a "bug" that can be fixed.

 

Here the pics:

 

 

Files used:

 

- XPMS 1-92 NMM-BAIN INSTALLER-26800-1-92.7z

- SeveNBase Bombshell NUDE more BOUNCE-36992-3-2.7z (---added TBBP butt bones---)

- All in one_Breast physics-Breast collision-HDT Havok Object

 

I would be glad, if you could give me some tipps.

 

Thanks in advance!
