The Octane Render plugin for Cinema 4d dev, offers us in his latest release, a scatter feature (more or less unexpected).
The tool is at the embryonic stage (according to the dev), but it is already very usable.
The main asset is handling a significant amount of "clones" with unparalleled ease in cinema 4d (only my opinion), and a render return almost instantaneous.
Here's my little video showing the painting "live" of a meadow / lawn on a polygonal surface.
