I have seen many cases where parts of the HeightField are transformed into mesh(for example: https://www.sidefx.com/forum/topic/68147/), but how is this done?
The Convert HeightField node does not support access mask and can only convert the entire HeightField to a mesh.
How to convert HeightField to mesh by mask?

You can use a HF Cutout by Object node (https://www.sidefx.com/docs/houdini/nodes/sop/heightfield_cutoutbyobject.html), which will convert the Height Field into a VDB, then convert it to polygons with a VDB convert node.

大卫·米奥齐Thanks for your reply, but this way can only get regular areas, and I want to get some specific areas by Mask By Feature, this way doesn't seem to work.

The channel used for cutout is Alpha, although getting houdini to understand that the layer called 'alpha' is for cutout is another problem entirely.
