.Map :: MoHAA Mapping

Hii,..
I'm kinda new user of mohradiant however i used to do maps in Q3radiant,.....ther's just a little diff. in between,....
the prob. i faced here with the Camera view setting (i GUESS),...
the hole textures r turning to b black in the camera view port whenever i do almost anything (creating new brush,clone brush,extract,...etc)
and they come back normally when i change texture view mode to trilinear, bilinear,bilinear bitmab,..,.....then turning to b black again in the 1st moification,....and so on!!!!
any help plz??
thx

It may well be a graphics card issue, you might want to look into that.

i tried that,.looking at its manual,...it's supporting openGL,...it's G-force4 MX,...
ummm,....isn't it settings matter?

Don't use "real lighting" in the editor options.

thx tltrude,...it's working
