I can use it in 19.5, it's no problem at all.

But in 20.5, I can't even activate it. I can draw the lasso tool but that's it, there is no masking on the geometry(the red area). How do I activate the node on 20.5?

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

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.

Could it be a GPU driver issue?
Otherwise I'd definitely drop a bug report here: https://www.sidefx.com/bugs/submit/ [www.sidefx.com]
The support team are very good at responding to these sorts of issues.

I think all these issues appears since I update my window 11 to 24H2.

Winodw 10 is working fine with every Houdini versions I think. All my Houdini issues are coming from winodws 11. Especially since updated to 24H2.
