Hey all, I'm a graduate student working with a team of students developing a Team Fortress 2 map for a class. We're having a rendering issue that we could use some help with.
We have an underwater cavern below the center of our map, and there are no issues if the player is above a midsection in the area. However, if the player is low near the ground and looks up, the above geometry doesn't render.
I've provided some screenshots below:
Near the ground (skybox shows through):
Moving a little further up, skybox no longer renders, and instead everything is black:
And just above is the "midsection" line, after which the above geometry renders normally:
Looking down from there, you can see where the geometry nicely divides the space into "upper" and "lower" halves. I've tried to draw some lines to point out the exact division, where problems only occur at a height below those lines:
Any help would be greatly appreciated. I'm not terribly familiar with Hammer, but my guess is that it's either a Visleaf issue or I'm missing some sort of water rendering entity. (Or, perhaps I simply misunderstand how water works and have placed improper water brushes in the space...)
EDIT: I think one of the problems might be that there are water brushes at different heights at different parts of the map. If that's the problem, is there any way around it, or is that a strict limitation in Hammer/Source?
