Can't find Blueprint Brush in Landscape tab

Hello everyone,

I’ve checked one of [latest Feature Highlits videos][1].And after investigation I didn’t find Blueprint brush in Landscape editing options. I’ve tried to find it in 4.25 Preview 2 but I’ve gor same result(cool new landscape menu and no blueprint brush in it). I have enabled Landmass and tried to pull BP on my landscape but spline UI is partially missing probably due to I’m not in Blueprint Brush mode.
Please clarify what I’m doing wrong.
