Adam. There’s tons of videos that highlight the strengths of Krakatoa. I think the guy is only being moderately sarcastic, assuming you would already be familiar with the tool.

“KRAKATOA offers both Particle and Voxel rendering modes using the same source data. It supports volumetric and additive particle shading, texturing, high-quality particle self-shadowing and shadow casting from and onto matte objects. Per-particle Scatter, Emission, Absorption and Density data channels, as well as various Light Scattering models allow deep levels of control over the final image. Motion Blur and Depth Of Field camera effects are naturally supported.”
Krakatoa relies heavily on particle density to get the volumetric look that it’s famous for, and thankfully the new xparticles is up to that task. Without multithreaded support and the ability to produce 10’s (or even 100’s) of millions of particles, krakatoa would have been somewhat of a lame duck in C4D. Now that’s changed with the new xparticles, so we’ll have one of Max’s best tools at our disposal.
