I’m trying to make an apparently infinite looking ocean using a skybox with water. I want the underwater geometry to fog out and/or just be the same color as the underwater fog in the main map. I don’t want to see the 2D skybox while I’m underwater from the sides.
I took a look at gm_seastruct_v2, and he uses four black func_brushes in the skybox to just obscure any of the underwater skybox geometry. This flickers ingame between the underwater fog color and black, though. I tried to also do that by texturing the underwater portion of the map boundaries with black as well, but that left these crappy lines refracting through the water when you look at the sea from above.
tl;dr: how do I make the sides underwater not look like crap?
