MASH is a relatively new module in autodesk maya, the leading 3D computer animation software package. i just published my third or forth → tutorial about MASH in maya, demonstrating its basic behaviour in context with dynamic simulation of a thousand little cubes.
the tutorial is not about rendering. but (solid angle) arnold renders MASH scenes fast and reliably. here even with the always cool and somewhat delicate effect namend „motion blur“. pixar, by the way, holds the patent for the first motion blur algorithms. it pays the pension of several employees there.
