let me say this real slow..
light_enviroments always work if you set them up properly..
if yours doesn't, then guess what? its not the lights fault, slow down quadruple check everything if need be..
let me also say, if any of the other lights work and the environmental doesn't, it can mean only one last thing, you have no sky, or it isn't a real sky..
a skybrush cannot have any other texture on it, it must be 100% skybrush, or the light_env. will fail..
i am 100% sure of this.. go back and recheck your map.. or post a link to it and i will..
