Tutorial for making terrain, in this case, "moving" water. 1) Start with constructing a simple frame to pour the water into. It doesn't have to be water-proof, but imagine something as thick as honey shouldn't go through any cracks.
2) Add contraptions from where the water flow would exit.
3) Pour some EZ-water onto a bent surface, like a bottle, and then snap it of and cut it into a size wanted. Else, you can pour it over a straight surface and bend it by hand a little, while still warm.
4) Glue the water in place. You can use water-effects, if you fear the glue will show through. Although, it probably wont. My didn't. 5) Add details, like corpses and rats and what not, and paint it all.
6) Pour heated EZ-water into the fram. Make sure not to spill on anything that it could stick to, and don't get your fingers burnt, this shit is hot! As it's starting to dry, use a stick to make splashing effects where the water hits the surface of the non-moving water, and also where the water ejects from the pipes.
7) Mix water effects and white paint and paint places where it would be natural for foam to end up, like around stuff sticking out of the water, where flow hits the surface and stuff like that. And voila! You're done. This took me about 2 hours to complete from scratch.
Hope you liked!
