Update: Still dying at the start, also, I just realised that ALL of my brushes aer invisible in-game (they appear as they should inside of radiant) all of my props and such are visable tho, and I assume why I am dying is because the player falls to the death because of the lack of brushes. Usuualy, you get the game over display immediately as the bo3 fades out from black. Sometimes you can see your first person hands and they look fullbright, as if the player fell out of the sun volume. This is not due to the skybox, I even prefabbed the map (excluding skybox sun and all those things, and put it into a new default map, resized things accordingly, and still have the same problem. I am pulling my hair out because of this situation, again if anyone can help, it would be appreciated.
