Thanks for responding to my issue. Z-fighting was the first thing I thought of when I saw the problem so I moved the brushes about to make sure there weren’t double-ups occupying the same space.
Sorry the last screenshots were a bit dark, I’ve taken some new ones. It’s hard to capture however because it only seems to happen from a distance.
The first screenshot is close up roughly where on the wall it seems to be occurring, you can’t see the problem in the screenshot though because like I said, only happens from a distance.
The second screenshot shows the problem, the hole that appears in the wall is right down the end of the staircase, it looks like a bright segment on the left. Depending on how I move the camera (mouse) around I can get it to occur on the right side and even on the end wall panel.
Lastly you can see from the outside the huge brush I’m using as the wall of the entire stair case. I’ve actually tried using 4 smaller brushes arranged in a diagonal to cover the side wall of the staircase, had the same problem though.
Not sure if any of this info will be of any help, but again, thanks for the assistance.
