As a test of the ability to overwrite existing armor designs I've created a mod that replaces the robes with cloth armor designs (normal clothes) Download it here:https://www.sendspace.com/file/iz1vgaINSTALLATION:
Place the files in of this zip into your data folder. Normally it would be:
/Program Files (x86)/Steam/SteamApps/common/Divinity - Original Sin/dataWARNING:
Do not place the files in /Documents/Larian Studios/mods as it won't work there. It must be placed in the data folder
Simply delete the files from your data folder. Alternately you can delete one of the files to only have one gender use clothes for robes.KNOWN ISSUES:
This mod cannot be toggled on/off from the mod menu, due to Divinity not currently supporting true stand alone mods that overwrite existing content. It permanently overwrites the robe models so long as it is installed.
This mod works with existing saves, so no issue there.
I have not personally tested how it works with multiplayer but others have confirmed it works without issue.
Secondary clothing such as Source Hunter Sarong won't show due to the game still considering them "robes".
Special thanks go to Norbyte for showing me how to make an overwrite mod.
