Once your heightfield is created and the erosion has run, right-click the heightfield node in the node network and choose Save As. Save as a TER format, then use a Heightfield Load in place of all your other heightfield operators for subsequent uses of the scene. Note that by doing this you will not be able to adjust settings for the heightfield operators anymore, so be sure you finalize your terrain before taking this step. You can of course keep the old heightfield nodes around but disconnected and inoperative, in case you later want to change settings, at which point you would regenerate, then Save As again, and change the TER that is loaded by the Heightfield Load.
