Hi, I’m constantly getting these weird glitches which I can’t explain. I’m using Gaia to create the terrain, Time of Day for the sky, and AQUAS Water. As you can see below, the terrain is missing at the top, but you can see the water and the sky dome. If I turn off the sky dome, the terrain is still missing, so it’s not that, same with the water.

My camera far plane is 600 but even at 2000 it still does it. My quality settings are

It turned out that the camera had occlusion culling turned on, and the ui canvas had been baked into the occlusion map.
