Is there anyway to somehow extract the ingame nif files, or atleast create new fx from them, and create a different texture (like changing the color of alchemiss_arcaneblast from purple to blue, without changing the color of her attack)?
in game fx are stored in art.ff. Just unzip what you want. If you change anything and dont want the original stuff changed, you'll have to make it an all new fx and install it appropiately. There's tips and tutorials about general fxing on FXForce.
Ah, thanks. I saw that before, but I never knew it was an archive.
