@Elliandre, it's actually a lot easier than one might expect. I started doing that kind of thing back in the TS1 era. I already had the tools because I did a lot of my own recolors and decided to poke around in someone else mods to see if I could tweak them a bit. Once I started looking, I realized "wow, this is actually pretty self explanatory."
Adjusting things just generally requires editing tuning file, which is like using a text editor. Not hard at all.
It's the mods that do completely new things and have *.t4script files that get more complicated and need some coding knowledge. I don't bother with doing those sorts of things even though I do have some coding knowledge. :lol:
