Flowing water?

Why is it that a water brush cannot vary in the Z direction at all?

Say, if I wanted to create a natural looking river or stream, it would be highly unlikely that the entire stream would be "flat." Don't get me wrong, the water in Source looks amazing... but it's all non-moving water. One would think that with the advanced physics this game is capable of, liquid would be something that could be mimicked, or is something like this too expensive for even today's juggernaut computers to handle with any sort of playability?

  • Water is exceptionally hard to physically simulate, both from a research perspective (working out how the hell it actually DOES move) and from a hardware perspective (actually simulating it in real-time). Water is still something the Pixar guys have trouble with, and they don't have the problem of having to render the screen 30 times a second. Still, I have to ask the question: What the hell is a PVS? --Graham 19:44, 8 Jul 2005 (PDT)
I added a definition page for PVS and made links to it in this document. --IanL 20:19, 8 Jul 2005 (PDT)


  • Question: If I wanted to make an area in a level have the effect of water (ability to swim up and down) without having any kind of water surface, how would I go about that? I am wondering because I recall an old Unreal-Tournament level where an area with water "rules" was used to make a sci-fi floating elevator-shaft thingy. Can one make an area with water "rules" in which it is impossible to die by drowning?

Water Troubleshooting

I have a scene in which the water is rendered upside down. By this I mean from the surface I can see through my level to my skybox, when I submerge the water refracts. I have water in my 3d skybox, equal height. Compiling in hl2. --FViral 16:33, 9 Sep 2006 (PDT)

Contact with world brushes

After reading http://www.student.ru.nl/rvanhoorn/optimization.php?chapter=notices I discovered that water brushes may not intersect with world brushes (such as skyboxes). I spent several hours fiddling with my map in Hammer before finding this. Could someone with a bit of knowledge on the subject add a warning and explanation in to this page.
