This just a quick mod I whipped up to redo the vanilla saber colors.
I re-made the saber textures from scratch, implemented the animated texture and added grain to the texture. As a result, the lightsaber blades will appear to have a slight vibration to them, which gives off a better and more lively glow.
All the textures are included, (even for Kotor 2), so just drag and drop into override.
I tried to upload a gif as the screenshot, but I may have to link a youtube video instead if the animation doesn't work.
