I see - I've changed the position of the SkyZoneInfo and, as you say, it works.[NBK]DxTrEm3Fx wrote: ↑Thu Jan 28, 2021 3:09 amThe original mapper wanted to keep the ground on the same plane as the map so he placed the zone info in the Skybox in the center of the bottom of nonsolid brushes. The Zone info in the skybox is the camera that projects the fake backdrop. This is what is causing the HOM effect. If you adjust the zone info so it's not in the center it works fine. But the ground in the skybox lowers itself which I assume he didn't want to do. I have tried to change to semi-solid and solid nothing works. I still get the HOM.
Before After So now it's playable with no nasty sliding textures. Thanks for that
