Hello all. I'm trying to work on my first map, but everything goes wrong when I enter Sapien. First off, there is no sky, only a purple screen. When I run radiosity, the numbers don't count down but instead go automatically to zero. The level becomes visible, but it is all black. I can get it ingame, but there is absolutely no light at all.

Any idea what could be causing this? Any help is appreciated.

Unless this was supposed to be an indoor map.. then you need to add light fixtures through sapien and redo radiosity.

Unless this was an indoor map, then you dont need the sky to cast light/shadows.

I fixed it, my materials were just misnamed. Now that I have that sorted out, how would I go about using multiple shaders? One for the street, one for a building, etc. Any good tutorials anyone can point me to?
