Textures going black in game

I have 2 building inside a sky box which has an env_light. In one building i have 2 light_spot's as you walk through the building with the light_spot's the inside froom somethings goes black then back to normal...take a look

Black Texture

No Black Texture

i've tried putting a cubemap in the room and selecting the roof/floor but it doesnt seem to help

anyone else getting this problem?

I've had a similar problem before and it was because a cubemap was
pointing at the textures. Try putting the cubemap back in the room but
not pointing it at anything. That worked for me.

I had this same problem- Replace any textures that have the word "model" in them. Model textures can't be used. (eg. models/props_c17/furniturefabric003a)

The easiest way to do this is to browse your used textures- check the box that says "Only Used Textures" (in bottom left corner of texture browser)- and use "model" as your filter.

Any textures that come up need to be replaced.

----same answer I gave here: http://www.snarkpit.com/forums.php?forum=6&topic=2826&17 ----

I've been able to use model textures okay...

I had some work for awhile too, then I got this problem. If they work- kewl. If the textures start to go black- keep this in mind.

I have the same problem, so instead of posting a new topic, i wanted to reply here saying THAT when looking at the wall they turn balck then go back to normal color, its like they are flickering, i dont know why is that, But i hope any one could please help me in this :smile:

thank you
