Reflections through wall.

Basically behind this wall there is a room with dev textures applied.
But from other room, wall reflects that dev textured room.
How can I block it so that it reflects only specific room?

In the room thats not dev textured, select the cubemap in there, click on Brush faces, press pick, and ctrl+click on the face that is reflecting odd, and it will force it to reflect from the cubemap you selected.

First, if that wall is one continuous piece between the two rooms, break it up into two walls.

Second, you need to add more cubemaps.

Edit: ninja’d damn it!

Firegod522 : Gonna try that.

darkspork: no it’s not a 1 wall, it’s a different walls and I even made corners to match not like go in each other
