Hello all. I'm having some trouble importing a heightmap image into the G.E.C.K.'s Heightmap editor for a new worldspace I'm planning to create based on Richmond, Virginia. Following http://forums.nexusmods.com/index.php?/topic/517230-tutorial-converting-a-dem-to-a-heightmap/ tutorial, I got most of the process finished smoothly until I actually got to importing the .raw 16-bit image files. After converting the RVA heightmap image obtained from http://cumulus.cr.usgs.gov/webappcontent/neddownloadtool/NEDDownloadToolDMS.html?nLatDeg=35&nLatMin=15&nLatSec=SS.SS&nLatHem=Northern+Hemisphere&wLonDeg=116&wLonMin=41&wLonSec=SS.SS&wLonHem=Western+Hemisphere&eLonDeg=DDD&eLonMin=MM&eLonSec=SS.SS&eLonHem=Western+Hemisphere&sLatDeg=DD&sLatMin=MM&sLatSec=SS.SS&sLatHem=Northern+Hemisphere&radio=on&State=California&County=San+Bernardino+County&Submit=Submit to greyscale, 16-bit, cropping a 1024x1024 section of the heightmap image, and saving it as -1_0.raw in photoshop, it DOES show up in the G.E.C.K. However, the issue is that when I hit save in the G.E.C.K.'s heightmap editor for RVA to make the heightmap's data apply to the render window, it shows nothing but spikes and ugly stretched out terrain. I'm thinking the image needs to be filtered or something I'm just not sure how. Any thoughts? Thanks in advance for any help.
