Houdini 12.5 3D FX water geo, evolving-sim grass growth, Mantra lighting in 3 main time-lapse river shots (bridged by 2D comp stills) at LookFX

after 10 second intro follows my animated-noise-rippled water out of the forest, we quickly ramp speed up to time-lapse rates of 2 frames per month then year, to show how the magical rivulet branched out to attract animals from all across the lands to follow the stream up to Noah's ark

to show the vast distances the rivulet branches spanned, my 3 main time-lapse shots were inter-cut with rapid-fire 2D stills, a few comped using frames of my Mantra CG water, to "leap" across the lands

instead of re-Simulating moss/grass growth for each 2-frame stage of rivulet evolution, I used animating noise to trim and modify grass blade height, thickness & colors to show it growing out, aging, wilting & dying along with the changing shape of my procedurally extruded and displaced rivulet bed frames of geometry

this really needs HD/UHD to see it clearly, but I also applied similar animated noise for additional water ripples along the banks and around rocks wherever they randomly broke up through the surface (in lieu of loads of costly new fluid sims every 2 frames)

my last shot ends with water ripples ramping back to normal real-time speed just before Noah's famous Doves fly down and take notice of this rare source of fresh water
