Issue with skirts in Fusion Girl

[eluddia]

For some reason both vanilla and modded outfits in my game have wonky skirt physics, with them seeming to be tethered to the crotch. I have the latest ZeX and Fusion Girl, have batch built all the outfits with build morphs selected, and made sure the body preset was applied to all FG categories. I'm on 1.10.984. I have attached my modlist in case I have installed something I shouldn't have or have not installed somethign I should have.

This is a bad skin (bone weights). You can edit the skin and smooth the bone weights with Outfit Studio.

To do this, open the outfit in Outfit Studio (from the Bodyslide) and switch to the Bones tab.

Bone Brush handling:
Bone Weight Brush + Mouse Button = Increase Bone Weight
SHIFT + Bone Weight Brush + Mouse Button = Smooth Bone Weight
ALT + Bone Weight Brush + Mouse Button = Decrease Bone Weight

Why do the vanilla outfits have this issue? I shouldn't have to edit the bone weights for the bodyslide files that came with Fusion Girl.

Counter question:
Why should vanilla meshes (which already have a bad thigh skin) be compatible with a non-vanilla skeleton you've installed?

Thing is, I do not have this issue with male characters despite using BodyTalk which ALSO uses ZeX like Fusion Girl does. Plus, I have used Fusion Girl before, and I swear I don't remember having this issue.

 

I couldn't find any examples of other people having this issue either, unless I missed them.

 

Also, keep in mind that this also effected modded outfits, and all outfits were built in bodyslide for Fusion Girl using the provided bodyslide files from Fusion Girl.

I've told you the reason for the problem and even the solution. Do what you want with this information.

PS: Men's skirts are a different Nif, meaning a different mesh with a different skin—just as a heads-up.

In vanilla, long skirts, robes, and coats have physics. havok bone cloth. These are bones that can be added in 3ds or copied to nifscope. I don't know of a way to copy or edit them in os. Without these bones, you can get an acceptable result, but it will still look worse than the original.If anyone has come across a manual on adding/editing these bones, or knows a way to add them to 3ds with bgs nif exporter, it would be a great gift for the modding community. I know there are people who work with these bones. Hairstylists, clothing makers, like vtaw. But none of them have ever created a manual.

I tried smoothing the bone weights, but I don't know what I'm doing so I managed to not fix the problem while causing new issues.

 

Unless somebody else has had this issue and has made a fix, I'm probably better off cutting my losses and abandoning Fusion Girl.

Upload a Skirt.nif and your Body.nif (both from Outfit Studio). Then I'll take a look at it in Outfit Studio and maybe I can not only fix the skirt but also take a few screenshots so you know how it works.

I found a mod that has its own bodyslide files for the vanilla outfits that does not have this issue. For some reason, it's only for the bodyslide files that come included with Fusion Girl itself. The issue is also still present on modded outfits, so I guess some people did a better job at creating/converting to Fusion Girl then others?

That's right.
Most people just copy the bone weights, and that's not enough for coats, skirts, etc. Then you get this effect.
But there are also people who know this and make an effort, and thus do a better job.
