I don't understand. You are talking about some piece of clothing that seems to cause butt deformation but on the image you posted all I'm seeing is a completely naked char and no clothing at all...
It would be helpful if you could name the specific pieces of armor or clothing that you're having issues with.
Also please never use imgur again on these forums, it actively blocks loverslab.
That's news to me.
Also sorry about the images. I was demonstrating a tassle from the Blade and Soul pack I linked as an example but didn't have enough time to make more image examples.
Here's some more images if this helps of three outfits - two from the UNPB Blade and Soul pack that has full HDT, and the other the Christy and Lei Fang outfit mod with full HDT.
The Blade and Soul outfits mostly work on their own unless the clothing over the butt has HDT. The two outfits I'm showing here both look fine without the tassle I'm using as an example. When the Tassle or Tail are put on - even though they are just accessories - it inflates the HDT butt outwards and make it either rigid or spaz out.
It's worth noting that there are many other things similar that the Tassle in the B&S pack, such as tails, or belts or so on that go near the waist or the backside.
No clothing version to see the comparison.
The Lei Fang Dress with HDT on it - Works best to save both images and flip between them quickly. The rest of the body does not change shape other than the butt.
So yeah. Not just restricted to accessories like the Tassle, but to dresses with HDT on them as well. Oddly, no issues from the chest or legs. Just the butt. Though I have an HDT cloak from a different mod that works perfectly fine and doesn't do this. So color me confused.
Also worth noting that just about everything I've been having issues with are UNPB HDT BodySlide conversions. But then again, so is the cloak and the outfit that came with it.
So once again, color me confused.
I feel you. I can't play without AIO anymore, since I can't find any interest in Skyrim without sexlab mods as I couldn't play it without SkyUI long before and so on... Before you start to reinstall things, you can try different HDT xml's and be sure to use latest version of skeleton extended. Not sure if it helps, just a feeling.
I could. And I believe I am using the latest version of the Skeleton. Though the last time I tried to manually install and HDT XML I think I fucked something up.
I'm using the version that came WITH AIO, so odds are that version is out of date with the current skeleton.
Will make a back up of whatever files it's going to replace and test it out. Going to assume I can find the latest on this thread section.
EDIT: So apparently, I guess the HDT Naturalistc XML FOMOD thought that the AIO was a newer version than it and I clicked the wrong button, uninstalling AIO. Re-installing it no. Either way, I don't think it'll be a problem, but it's more of a stupid over site I should have paid attention to.
Either way I'll get to see if simpley reinstalling it will work, and if not I'll try the HDT FOMOD without screwing up again and see if that helps.
