The waterfall cascades were created using two terrains: One for the forrest environment and one for the cascades. The start for the forrest water is taken from David Birdick's river rapids mixed with foam and sea water. Some splashes and turbulences are added using volumetrics. Full effects for the water are reached by using a second " green/blueish" sun. Only postwork applied are small adjustments in hue and contrast. Sorry for late entry due to business travel.
