I’ve got a problem with one of my maps. A small gap appears at the intersection of my walls.
I know it has something to do with the wall brush being shifted during compile so the wall face is nolonger in the proper spot. I also know that you can see through it because the engine automatically changes the side of the wall to a nodraw texture, and with the main face shifted, the effect of the side on joining brushes is visible
This is what it looks like in hammer:
The red line indicates the brush face when in-game and the blue circle indicates the resulting ‘gap’
How do I correct this?
