You can convert heightfield terrains to .TER. If you are using a Heightfield Generate to create your terrain, simply Generate your terrain then Right-Click on the Heightfield Node and choose Save As. You can then save a .TER. If you are using procedurals, you can convert into a heightfield by feeding your procedural terrain network into the Shader input of a Heightfield Generate, then Generate and right-click, Save As, same as above. You can adjust the area and resolution of the heightfield with the size controls in the Heightfield Generate.
