All right. Did a search and tried remaking the brushes as Caulk Terrain and then making them structural again. Still nothing helps.
I have had this problem with both sections from day 1 that I’ve compiled the map.
It is a common texture for both places used .
Is it possible that during the BSP or VIS process that a brush near the area is affecting the brush? I think when it gets cut up that something becomes messed about it and you can see the cut lines when you walk over…then it goes all trippy.
Brushes both get the see through effect and that dizzy moving effect and are in complete different areas on the map.
Already did a Brush Cleanup and there are no errors during compile. And I have remade the brushes numerous times. Both brushes are just a basic calkterrain square, textured with textures/battery/sand_disturbed
