I do this for the screenshots to be perfectly honest. ECE is way better than racemenu in my opinion. and i have no idea how to convert these to racemenu files,but they do look great in game and play flawlessly. i play my game with almost 700 mods and have no issues. the list is long i know but mostly add textures. so if ur up for it you can try and get the same results by inatalling these:
