📋 About This Mod

What does this mod do?

This is an updated version of VSU for OStim (NG), rewritten to work with OStim Standalone's new scripts. Just as the previous version, this mod is a modification of OStim's undress script that uses registered config files to swap version of armour/clothing. In 1. 1, you can now use high heels mods without issues, just make sure you select the "heels alignment" on in OStim MCM.

This mod uses various states of undress framework to automatically swap to a different version of an clothing or armour. For instance, you can have Caenarvon's magecore robe switch to the "lewd" version for animations involving breasts (stage 2), and then have the panties do the same thing but for sex animations (stage 3).

You can also have clothing stay on even if you tick the slot in OStim undressing MCM, which is useful if you want to (as an example) undress slot 32 (body) in general but want to keep certain outfits on that occupy slot 32. You can also have clothing stay on even if you tick the slot in OStim undressing MCM, which is useful if you want to (as an example) undress slot 32 (body) in general but want to keep certain outfits on that occupy slot 32.

Here is an example of multiple outfits - Caenarvon's magecore and cosplay pack, swapping variants to "Stage 2" which is for foreplay animations involving breasts or oral (if using expanded version):
