Yeah, I timed it. 15 minutes per brush stroke (and I restarted but it wouldn’t go away).
I’m uploading it to McNeel (though it’s a personal hobbyist file, so it’s not sensitive in any way), so hoping someone over there will try to make this selection here below using the _Selbrush and see what the results are (or rather when the results come in):
I don’t know about you, but to me, 15 minutes isn’t exactly “realtime”…
