I map a small basic map and I had the textures had I wanted them (picked a texture then made the brushs) and after I compiled it and got into the game its all just pink and black boxs

anyone know why?

sounds like you made the brushes from textures in a wad file that engine cant find, e.g. need to put the wad files in the halflife\nsp folder...

but send us a screenshot anyways so we can see...

only used textures from ns.wad and ns2.wad... I think

Yup, it can't find the textures. If you say you only used textures that you had, it could possibly be a problem in the compile process. Try opening up your map in hammer and make sure there aren't any white textures anywhere, If all else fails, select wad-include in batch compiler and set it to include both of the wads you used.

thx Xyth & ShenTraX, I got it to work
