It seems to work fine here - Houdini 20.5.435 / Windows 10.
You're activating the mask state by hitting Enter while over the Scene view?

I'm on 20.5.370 - maybe it's got an update since then. When i drop the node i hit enter and can draw a shape, but mask remains empty no matter what i do. If i invert the mask, i get full mask. So there is some issue with a drawing getting translated into a mask. My workaround is to draw a poly shape, extrude it, and use Mask from geo instead.

Hey, I've got the same issue. hf draw mask SOP doesn't seem to work Other mask nodes work.

good to know, thanks for heads up. we'll update as soon as we can.
