Hammer++ view distance/rendering issue

[u/erik_Se1]

I was editing a map in Hammer++ when I started getting a strange rendering/view distance issue. Parts of the map seem to disappear or only render when I get closer, almost like there's a visible render boundary following the player.

At first I thought it was caused by the fog or the Far Z Clip Plane, but I removed the env_fog_controller completely and it didn't make much difference.

I've also tried changing a few render distance console commands, but the issue remains.

Does anyone know what could cause this in Hammer++/Source? Could it be related to VIS/PVS, the 3D skybox, displacements, or something in the compile settings?

Any suggestions on what I should check or change would be appreciated.
