A step forward from my previous video, I tried to apply the sand effect to a deforming object which was a bit of a challenge. But I was able to achieve sth here I tracked the surface velocity and applied it to the 20,000 volume particles while physics and joints are active, joints started to break gradually based on velocity and collision. Those particles at a later stage drove 1,000,000 which will give the sand look, and I also grabbed the texture coords from the unwraped Zombie surface.
Of course rendered in Krakatoa with some motion blur.
