Hello,<br><br>I'm attempting to export a DEM to a terragen file and I've run into the following error message. <br><br>ERROR 1: Inverted, flat, or unspecified span for Terragen file.<br><br>There isn't a great deal of lit in the manual regarding terragen exports, and I'm wondering if anyone has any personal experience doing it, or knows a better method.<br>
