Ok, i know this is a long shot, Im currently looking for and old mod for lightsaber blades. It was something along the lines of being called "Refined Lightsaber Blades" It removed the Boxy effect of the graphic and made it sharp and refined. it also stayed true to the original colors. It was on PCGM one apon a time ago. If anybody has it i would be eterneally grateful. i cannot remember the author.
Edit* Also i think it was oringally a TSL mod but since the textures were the same name it was also usable for KOTOR
