I have a deformed terrain model.
Above it I copy tons of trees, plants and rocks objects.
Then I use bullet physic to place those elements (randomly) on the surface of the terrain.
It's working, but I would like the falling objects to stop moving on impact and block their rotation (prevent them from rolling).
I tried to activate all the limits, all link types and bullet properties without success : everything continue moving and rotating (on the steep hills).
In Vue d'Esprit there is a drop function that does exactly that. You place above then hit the drop button.
I hope to use this technique eventually with "Force" to place/scatter objects on objects.
