Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods Skin and hair color refernces in properties.lsx

from the top of my head, create a new mod which has a dependency with main. (check the box when you create a new mod with the editor) Set a menu level and as starting level set it as CharacterCreation. You now have a working mod in which you can edit stuff for the main campaign.
put your
"Divinity - Original Sin\Data\Mods\Main\CharacterCreation\Properties.lsx"
into
"Divinity - Original Sin\Data\Mods\_YOURMODNAMNE_\CharacterCreation\Properties.lsx"

should work fine for mp now
