Was testing a lot of things simultaneously here: Blender stylized chars, mechanical face rigs, water/ocean/grains FX in Houdini, Mantra rendering and the pipeline Blender-Houdini as a whole:
Modelling, rigging and character animation done in Blender.
All the rest is Houdini 16.5.
Has a couple of glitches though which cause flickering at several points, one due to a bug I wired into the sand material shader, and another one causing sand grains to change position every frame. Unfortunately those frames take their time to render, so I decided to go with them for now, maybe I’ll re-render as soon as I have more compute power around.
Anyway, I feel Blender and Houdini team up nicely.
