Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General D:OS2 on GOG and Steam Workshop content.

Nexus has quite a bit more mods than does the workshop for D:OS 1 but that has more to do with the nature of the game than the community.

Hopefully modders figure out how to package their minor graphics mods and such properly in the editor so they can be on the workshop as well. Unfortunately in the 1 editor that is quite fiddly to do, thus none of them are on the workshop.
