Just a few render tests I did with the Frantic Films Krakatoa Renderer (Beta 0.9.13).

Animated surface with 8 million particles (rendered with Krakatoa 0.9.13, color correction and glow added in post):

A basic particle flow + krak test with 6 million particles.
[MEDIA=7]

[MEDIA=6]

Just a simple explosion test with a FumeFX pass. Particles follow rigid bodies before they raise up.
