cant find the post with monkey mod so i will just say this. with monkey mod (i believe 1.8.8.7?) it has a option to just remove or add any clothing. but say the model has boyshorts on and you interact with them, the mod will say they arent wearing anything. like in the image it should have g-string as a clothing option but doesnt because i interacted with it. odd bug but yea it happens.(also ignore the boyshorts thing i was testing with it)
As explained in the release notes, Monkey does not support displaced clothing.
When you move say a boyshort, the game will delete that garment and replace it with a hidden one like 'boyshorts_ExposedAss'. This is why Monkey says it's not there.
As 9.6 seem to now 'save' displaced outfit, I may revisit what I expose in the next UI patch.
-T-
P.s. the new custom cloth system will not support displaced clothing at least initially. Both the cloth editor and custom clothing should be done by the dev. What I provide is just a stop gap at best.
Edit: I checked 9.6 - while the outfit picture will show displaced clothing, the garment data is not saved and the game can't load it. It's a bug in the game code, and I reported it. Once the dev fix/implements this, I can take another look.
Edit 2: I may have found a way to support editing displaced clothing. This won't fix the game not saving outfit properly. If this proves safe in testing, I'll release this in the next version.
