tried it my self. I'm submitting it because I don't think anyone else has tried to share the toilet scene yet and i thought some people might enjoy it. Oh by the way it's my first mod so it probably has a few bugs. The hardest thing to make was the lightswing.
real time for demonstration purposes, and also some examples of what one can do with a lot of hard work with the particle editor. The most noticeable changes are to the weapons of the bfg, chaingun, and plasmagun. All their particle systems have been completely redone using existing Doom 3 particle textures and also extensive use of new custom made textures. There are also some other particle effects you will notice. Some other details are added decals, glossy weapons, textures for the tutorial room, and some edited/added model textures.
