Clipping with certain outfits but I've built bodyslide multiple times

[Idontknow9902]

Hello, I'm so very confused and I would appreciate some help from fellow modders. I've been modding skyrim for about 4 years now and this is the 1st time I've encountered this problem. This problem started with the outfit "Vtaw Wardrobe 5 - CBBE SE - CBBE SMP - CBBE 3BA - BodySlide" I thought I downloaded the 3ba version (but I didn't) so I thought it was my 3ba or XP32 skeleton and updated those to the most recent versions, after finally figuring out I hadn't downloaded 3ba for Vtaw, I downloaded the 3ba version and did the usual routine of running bodyslide AND I thought I had fixed the problem, The dress was not clipping through my character anymore and I closed the game not really testing anything else. Next time I booted up skyrim and put "Yorha 2B Boots" on, her thigh was clipping out of boots, when I removed the dress her thighs weren't clipping anymore. I tested some of my favorite outfits and sure enough the clipping was on quite alot of pieces. I've noticed the major clipping is only on stockings and bra's. So I reverted the updates on 3ba and XP32 skeleton and the problem still persists.

I'm very certain I'm using the same bodyslide preset, I'm doing everything I was taught and I cant seem to fix this problem, I would really love some help!
I've providing some screenshots of the clipping and my load order of my body setup. 

Any help is appreciated, Thank you for Reading.

Several reasons for this:

1. Unfortunately there's several different versions of 3BA, and the naming scheme is all over the place. For instance, you might find a "3BBB" outfit which is 3BA. You might find a "3BAv2" outfit which is actually 3BA, you might find a "3BA" outfit which is actually 3BAv2, you may even find a "3BA" outfit which is actually an ancient CBBE or CBBE SMP variant. The only way to tell which body type some outfit is is to inspect it yourself in NifSkope. Look for key mesh changes and NiTriShape name differences. Compare these to the body meshes from the original 3BA author.
2. The weightpainting on the outfit is slightly different than the body underneath it. Its becoming more common these days for mod authors to add weightpaint variations, especially on tits to make them behave more naturally to simulate clothing.
3. The outfit polygon count and/or vertex positions do not line up with the body underneath it causing polygons to move slightly out of sync (despite being weightpainted the exact same amount) in extreme shapes like when a character has huge boobs. Basically the outfit is too close to the skin. This issue is particularily annoying to deal with in Outfit Studio because it tends to only show up when you apply physics to your character, thus you're working blind in OS trying to fix it. Unless the vertices are far apart in which case it starts to show up with extreme slider values as well.
4. While most likely not the issue you're seeing here, Z-fighting and floating point inprecision is still a thing in 2024.
5. Doing body conversions, or setting up morph sliders in Outfit Studio using automated tools, usually does not result in flawless morphing. One slider that is guaranteed to always be broken is the Pregnancy slider. Another problem spot is negative slider values. These will always require manual adjustment and fixing to remove or reduce clipping.
6. It is very rare to see a community made outfit which is correctly (IMO) made when it comes to clipping and optimization. I'm no 3D modeler myself, but I've observed differences between vanilla game content (not only in Skyrim) and community game content I believe to be essential in removing clipping:
   1. When creating throusers for instance, do not leave the ankles and waist open but instead seal the shape at these points; i.e. instead of creating a pipe, create a solid cylinder. This has the benefit of hiding the fact that the throusers are floating slightly above the body mesh.
   2. Do not add polygons on the inside of clothing items if they're not visible. Why render these when they can't be seen?
   3. Remove the body polygons that are obscured by clothing. This will get rid of all clipping in: morphing, physics and z-fighting.

Considering this is apparently a Vtaw outfit, and based on what I've seen in Fallout 4 with Vtaw outfit packs:

1. They do not work well with extreme slider values.
2. They do not work well with negative slider values.
3. They may have minor issues with physics.

These issues are obviously not specific to Vtaw.

Thank you for the help! I realized it was my bodyslide preset was way too big, I forgot to teak it when I downloaded one from the Nexus.
