have a look at this image

any ideas ?

We can't really say anything. is that a displacement? a brush? is it clipped or is it carved or is it manipulated? More details...

Its a displacement
with a overlay

this appears only after a buildcube !

There's your problem :o

Try changing your env_cubemaps. Remember, faces that use cubemaps (such as displacements, since their shadowing is mostly dynamic) will use the closest cubemap they can find (if not assigned).

yep tried that same problem

does some very strange stuff on diplacements

any advice

Did you try running a full vis? You could also try using hint brushes. Since displacements are lighted with dynamic lightning (as far as I know), they light themselves considering the vis portals you're in.

You're using model/prop texture in world brush. That's why it looks like that.

will try a full vis later to see if that works

Are you totaly sure? I would have said it was a model texture too...

I know I did expeirence such thing with model/prop texture, maybe if you would post the actual texture name you are using, it would clear that point out. I have not had any problem using normal texture on displacement.

Try putting a cubemap right above the overlays. I have had some weird issues with overlays and physics props when theres not a cubemap close by.

texture on displacement is
