Some issues with meshes that don't show on BodySlide

[Skyrimfloo]

Hi there! I've been getting this issue for some time, at first I though it was some problem with my meshes or bugs in BodySlide, but now I'm not sure about it.

 

I can provide some screenshots later if anybody needs them. Basically, I've been working on a mashup and trying to adapt a couple armors to CT77's HDT body. It looks fine when I work in Outfit Studio, and it looks good as well, when I convert it using BodySlide.

 

When I get into the game, however, my character gets "crushed" breasts (they react normally to HDT, but they look flattened. Also I noticed some variation in the size of the butt). As an experiment, to see if the issue was part of the mesh or something with the game, I took the original body mesh from CT77's mod and copy&pasted the armor parts sans the body mesh inside that file with Nifskope.

 

When I did this I noticed that the body mesh from CT77's mod and the one from the armor (which should have been the same, since I used it as a preset for BodySlide when tweaking the armor) looked different, basically, the body from the original mod had bigger boobs, so when I copied the armor pieces into that file, the breast parts were clipping into the breasts. However, I saved it and checked it in BodySlide and Outfit Studio, and again, there the armors looked as if there was no problem, no clipping, no issues whatsoever. I converted the armors to my preset, checked in the game, and here the armor looked like in NifSkope again: the breast pieces were "crushed", but this time the body mesh was fine.

 

So, I have no idea of what's happening here. It looks like anything I pass through Outfit Studio is getting fucked up, and it seems to be related to HDT bones, since those are the ones that seem to be affected. I'm using the latest BodySlide, XPMSE and CT77's Remodelled Armor files, and I'm using the HDT All-In-One from here. None of the armors from CT77's mod have this issue even though I've modified them from Bodyslide, so it doesn't seem to be messing up anything in itself, being related only to Outfit Studio.

 

My best guess is that somehow whatever I do in Outfit Studio I'm probably downgrading the HDT bones (since they changed their naming recently in XPMSE), but I'm not really sure of how to solve this. Anybody has some idea of what's going on?

You can try the OS way, but OS AFAIK still does not handle skin deformations properly.

I highly suggest using Blender/3dsMax or even gerra6's Mesh rigger with the 'flatten skinning' option for fixing weights.

When you copied CT77's body into the outfit did you also do a copy bone weights for the other meshes in the outfit to have them line up with the bones in CT77's body.

 

If not that is the problem.

 

The base shape mesh in the nif file is calling on one skeleton and bone weight.

While the other parts of the mesh are calling on the old skeleton and bone weight.

They need to be the same for the nif file to function correctly, otherwise you can see strange things like sunken breasts, extended breasts, breast bounce for the armor being different from the base shape, and butt bounce (especially if the armor was just bbp and did not have butt bones in it).

 

Once you do a "copy bone weight" into each part then you want to check for any over spray (aka stray weight painting). As you could end up with bone weights in wrong areas (like the left thigh on the right thigh, which causes spikes to come out of the thighs in game, but don't show up in nifskope or Outfit Studio). Sometimes the breast bones will end up on the apposing arm (like part of the left arm will have some of the right breasts weight painting on it).

 

Do the copy bone weight and check for over spray and you should be good.

 

Or do it Bla Bla's way...

It's what blabba said. Of course, I hadn't updated the default skeleton that BodySlide uses. I assumed it would pick the one in the Meshes folder, since I never saw any information regarding that (and it kinda made more sense to me, to be honest). I guess I gotta pay more attention to the description of these things...

 

Now I'm getting a minor issue with the shape of the breast, but I think that's just me borking the body meshes in OS, so no worries here yet.

 

Thanks for your replies!

The latest BodySlide comes with the latest XPMSE skeleton, though, so there's no need to copy it. You must have installed a reference skeleton "fix" mod at some point - those aren't needed anymore (or you aren't actually using XPMSE in-game).

[Skyrimfloo]

well, I didn't install anything like that. This week I've been updating my modlist since I didn't play in a long time, and I updated both XPMSE and BodySlide. The skeleton that was used as reference was the "xpms.nif" one, not "xpmse.nif", and I don't remember ever changing this (otherwise, I'd have known what to do). I could have done it and then completely forgot about that, but I have no idea of why would I do such thing...

 

In any case now it's fixed.
