These blocks should be used for scattering. And last thing - Rhino performance - As for now, using Rhinoceros 5 + V-Ray 3.60.03 the most effective way is to convert geometry to proxies and then to blocks. This makes scattering process a bit faster and eliminates the issue with object under the surface. For the Normal orientation - sometimes it's a good idea to mesh the surfaces you want to use for scattering, check normals of these meshes and join them. Then we have to adjust these accordingly.

Regarding the Rhino Grow - we use it all the time, however it needs manual refinement after the scatter is done - Plugin doesn't position objects evenly and leaves empty areas, while at some areas, the population is too dense. Hi! First of all, Rhino grow will be obsolete in a few weeks - new scattering plugin is under development and it looks very promising.
