*if it appeared but it is grey and has no texture u must press "~" again and then type in "radiosity save" and viola your bitmap appears.
*if your map did not appear at all just reopen your senario file and try it again using "radiosity_quality 0" press enter, then type in "radiosity_start" and most likely u will have to wait a while for it to countdown (depending on how many polys it is) and then type "radiosity_save".
ok, it looks like your level isnt textured. i hope you know how to do that, if not jsut ask us. also you dont need to set teh radiosity quality, the default for it is 0. also don't forget about radiosity_save so that the radiosity is saved
SHADERS! make sure that your ground has a shader! simple problem that Ive broken many a keyboard slamming my head on it because of that silly little problem!
+sky just makes the faces that have it applied invisible and shows the sky, thats it. *just like im marathon where you apply the sky, the material is solid, but it shows the sky instead*
