Hi Mojachiee,
You can increase the brush size f the brush if you need. The default size 512, but you can increase that to any number you like. The slider maxes out at 8192, but you can type in a number if you need as well.
A word of caution though. If you’re placing dense amounts of foliage or poly heavy foliage this can lag a lot because of so many instances being placed at once.
Thank you!
Tim
