Hello,

I want to use a 2d texture as a mask for the heightfield. But all I'm given is a node like heightfield_maskbyfeature or heightfield_drawmask . I tried to use the node like attribute copy, but i couldn't make it. If you know how, please help me. Thank you.

Hi, you will want to use the HeightField File SOP. You can load images from disk or from Houdini's compositor (COP networks).

Oh, I didn't know there was a mask option. Thank you!!
