finally, i had finished sets of the nodes in nuke for my waterfalls. i can change the look of the waterfalls in realtime and place it in the 3d space in nuke. so i can fly around in 3d-space and place so many waterfalls i want… the rendertime takes about 5 seconds in nuke (incl. displacments) with this different waterrfalls. (all created with same base-layer).
waterfall 2.5
