And waterfalls of... well, coolant. Which is more or less water.
In the marked areas should be metal grating, from the metal grating should be pouring coolant from all over the map (if you need an excuse for where to run an aesthetic pipe, this is probably your best bet).
So here's the trouble.
HOW TO MAKE WATER FALL?
I can make stagnant water, but I'm wondering if there's a waterfall texture on the order of co_daimos_beta5's sewers (but more opaque maybe?) and if there's a corresponding "disturbed water" texture.
If not, then are there any good tutorials somewhere for making HL1 textures?
