Someone else might have a more complete solution to this but a workaround I’ve found for this is:
- Clicking only once and dragging instead of placing multiple circles, then you won’t get any overlap
OR - Using a massive 20,000 brush size and clicking once to cover the entire area, then going in with lasso tool to select and delete any foliage you don’t want
You can set a positive radius on the foliage’s painting settings too which may help keep them distanced so they wont be denser on overlapped spots
