So I'd like to offer multiple versions of my mod which only differ in the resolutions of the textures included with it. Mod A offers textures that are 2048x2048 and Mod B offers 1024x1024 but they share the same esp. What is the best way to go about doing this?

Would esp file names have to be different between the two in order for Steam to see them as two separate mods or can I just change the the mod titles? I would like to keep the esp file names the same if possible. Also I'm assuming it's not possible to upload multiple esps in a single mod? Thanks.

I think it is based off of the filename. So I would suggest uploading a modname_2048.esp and modname_1024.

If I am wrong, someone will correct me, I'm sure.
