Gary,
I went to USGS TNM Download and clicked Elevation Products, then clicked 1arc-second and 1/3 arc-second and 1/9 arc-second. then clicked search products. I downloaded the two GeoTiIFFs, "USGS_1_n36w083_20220512.tif" and "USGS_13_n36w083_20220512.tif" Then imported them to Qgis. I didnt do anything to them in Qgis. Just exported them as GeoTiffs, retaining the original file names. Next I made the Infs from each of the files, "USGS_1_n36w083_20220512.tif" and "USGS_13_n36w083_20220512.tif", using GeoTiffToInf.
I combined the "source" section of each of the infs into a single multi-source inf, with the appropriate header and additions you showed above. I named the Inf "2NC0_USGS_1+13.inf". I then resampled the Inf, "2NC0_USGS_1+13.inf", and created 2NC0_USGS_1+13.bgl. Added this bgl to 2NC0 Terrain/Scenery folder with the cvx_2NC0_ADEX_GGB.bgl you sent me.
Im getting some really strange looking landscape with plateaus and floating runways! Must really have something messed up now!!
