Thank you but I've looked at that post and from what I understand from it, its a method you use to edit or build off of mods you downloaded from a third party.
From what I understand when you download a mod from the workshop or nexus, even if you place it within your project folder within the Divinity engine, it wont register as a project that you can edit or build off of.
The post you link fixes that by creating a meta file that links the divinity engine to that third party mod for editing purposes.
