I have a problem with the foliage tool and the brush I do not see the selection area appear (transparent arch) although I adjust the diameter to maximum or minimum nothing happens. I don’t know if it’s because I added too much mesh (is there a limit)?
It could be the thing you are trying to paint has no collision. Or you have the wrong options selected
It’s what I said 
That default floor mesh has strange collision, just change it to ‘block all’.
Thanks
ok I just have to change the landskape?
Can you tell me more about this pb
Sorry for my english
Click the floor mesh, in the details
