Hey guys, I'm trying to create a river by using either particles or fluid effects on a nurbs plane (see below). I have a general idea how to make it flow and stuff, but I need to bridge a basic step before I can continue on my own, namely: I need to know how I can make part./fluids appear at the bottom points of my plane, and cannot go any higher than the top point. ( So then I would have my canal filled with particles, but now it's either overflowing or particles just run right trough my plane's moat, when I attach an emitter to a curve. ) I hope this makes any sense .
