Update. Another 10 hours today. Here are some random shots. At this point the underwater tunnels are finished and well lit, the main and supporting temples are done, and most of the map is about completed. Now I will start working on the shaders for the water to improve it (color and movement), shaders for the flags and 1up banners (so they will move back and forth) and some other shaders. Next I will begin to add sound files to things like the teleporters and other areas where I want to play a sound.
