I'm looking at rendering a height field along with a water plane and would like to clip the height field to remove parts that are underwater. Would anyone know if there is a way to do this without converting to polygons first?

Try dropping down a HeightField Clip node. Activate Min and turn off Max.

Yeah I tried that - it changes the min height in the height field but doesn't actually clip the surface below that height.
