PyroCluster for Mac

From Maxon Computer:

PyroCluster® allows animators to create dust, smoke, fog, clouds, fire, and other hard-to-create effects, and they all render in seconds! This allows animators the freedom to apply atmosphericeffects like never before, where they can freely add an effect such as flying through a cloud bank, with little regard to the impact on rendering speed.

Let the Particles Burn!
PyroCluster effects work from the data provided by any CINEMA4D compatible particle system. Those particles are usually set to a size of zero, so that they don�??t render and only provide 3D information to PyroCluster. Then, PyroCluster generates its volumetric effects during rendering, combining complex gradients with fractal noise to produce anything from rocket engines to explosions to puffy clouds or even waterfalls!

Real 3D Volume Rendering
In addition, PyroCluster effects are set up to work seamlessly with standard lights and the CINEMA 4D raytracer Clouds deform and stretch based on particle system action, and each bit of cloud moves and rotates based on the source particle system. PyroCluster introduces also a newly developed volume tracing technology that lets the user create amazingly detailed bumpy and carved surfaces without creating any polygons.
