By plugin I mean .esp file. There are two because one changes the creatures stats then the other changes the perks, so each remains optional however I want to distribute both. And no, there are no dds files used by me. I already checked the esp files with TES5Edit, I used it constantly to check errors before it is too late, so right now it says both are 100% clean. So, how to make a mod from that and upload it to Steam? And what is a bsa file, CK proposed me to make one. I got a few bsa files when downloading mods so I figured they are sort of packed archives when graphics are added, but not sure to what extent.
