I've also been doing some re-texturing. Increasing the resolution (size and depth) of textures and also making them a little grungier. I've also "borrowed" re-works others have done on some of the textures, though usually additionally modifying them further to match my changes. Though I'm probably going to abandon that going forward with the other levels because it's just way too time consuming.
I've done some tweaking of some of the LEC cogs. For example, the closer you get to the glowing signs, the more the sector tint changes to the color of the sign. If you shoot out the sign, the sector tint returns to normal and the 3do light attached to the sign is turned off as well. There's another cog that associates itself with one of the small lifts with a light. When the lift is activated, the light comes on. When the lift returns home, the light dims off.
Because of the texture changes I've made so far, I'll probably have to do all the Nar levels first. After that, does anyone have recommendations for priority?
