Well don't understand this prob
In radient everything looks quite nice, When i load it in cod2 you can just look trough the wall, didnt use caulk or somthing. So when your inside you can see everybody outside, but at the outside you cant see te inside strange things happens in the world :p. Can anybody help me

is the wall going into anything, like another wall, the floor, or roof?

no it isnt, all wall are the same but this wall is just weird

Check your compile log for duplicate planes. This wall brush might be one of them.

Try the above. Its unlikley but you might of used a decal instead of a solid texture. Just try re-texturing.

jep it worked

thx

What was the exact problem? Let us know. Was it a decal texture? Duplicate plane? Something else we should look out for? It's good to get this info out there for people looking for answers to problems. Thanks.
