Im also relatively new to Houdini and Heightfields, but I think your explanation of the different between heightfields and polygons is accurate, I have needed to "convertheightfield" node to turn to polys before applying UVs, exporting, etc.

The Material Bake ROP, Im not familiar with. But the "heightfield_output" has allowed me to export any relevant maps that I've generated in Houdini as EXRs.
