This is going to be one of those questions where the answer is staring me in the face.
I downloaded the USGS topo data and used MapMaker to export it, then put the exported files and the blank .wca and .wcb files into a new directory, all called the same thing. How do I now load the AH terrain files into the editor, so I can review/edit it? I can only seem to get the default terran to come up.
