Bodyslide preview different from actual output nif file

[odps]

Everything is good in bodyslide preview

But after build, it just changed. Any idea how should I save this problem?

The outfit studio project files are provided below

[NINI] Charles Rene Upper - UUNP.osp

[NINI] Charles Rene Upper - UUNP.nif

[NINI] Charles Rene Upper - UUNP.osd

I checked the project nif file, though the original file is good, after I imported it to outfit studio and modified it, it changes to the one in the second image.

[NINI] Charles Rene Upper - UUNP.nif

Hmm. Can you check if the clothing alone changes shape on increasing sliders? otherwise, it seems like a problem with body/ body texture. if that isnt the problem, then you can manually adjust the mesh by using outfit studio tools. irrc c5kev did upload a pdf for converting meshes to UUNP and CBBE here. that might help
