Hello, a guy in this video is showing:

That in the version 4R6 flatten brush was modified , i tried it and its true, his flatten brush behaves different from the default one in 4R6.
Where can one download the old flatten brush, do you have some idea? He doesnt say it in the video and i didnt find any link online.
