sorry for late reply. I didn't use the the offy= param, I programmed a piece of code for my app that offsets the mesh on the Y axis so it sits on the terrain without modifting the FPE. But yes you could use defaultheight = 50 or other value, I can't recall if the offy= param actually works. It's been a while since I tried. I recall offsety= param works though.
