Yes, thanks, I was aware of that - actually I was more looking for a method to spray object differently.
To remain in the example of scattered leaves: imagine a spray tool which adds objects with every click.
I click several times under a tree and each click I get more leaves, then I click somewhere around the tree to scatter some more lost leaves..
This is not really possible with the paint area as the distribution remains the same and therefor needs to be controlled with a mask too..
Right?
