Yader, (Derya Öztürk) posts a little hack showing how to evenly paint objects on a Surface using Cinema 4D’s Hair Module and the guides tools for controlling the distance the objects have from each other.

This is a neat hack if one has to paint objects onto a surface without overlap

Yader notes that you are able to paint objects on a surface without overlap using this techniques, and id you need to delete guides, you are able to do so by using the hair selection tools to select the guides and delete.
