Carbon Scatter is the most powerful population plug-in for 3ds Max, Maya and Cinema4D - and it now includes a vast library of 3D plants and billboards! The Carbon Scatter 2 plug-ins integrate e-on's patented EcoSystem™ algorithms directly inside leading CG applications, allowing you to populate your scenes with millions of native objects, and render them with your favorite renderer.

Now we can only wish that there were something like this for SketchUp - or to begin with, SketchUp could handle such models.

This video released recently demonstrates CarbonScatter's powerful capabilities and features.
