I used "sv_cmd radarmap" to make a "radar" image. The result did not include the entire map, but I converted it to .tga and plonked it in the .pk3 and it worked anyway — except that it still didn't include the entire map (the rear end of the blue base is missing).
Since this was a symmetric map, this was easy to fix with Photoshop. However, as expected, the objectives were still in the same place as they were with the original image. Is there any way to scale this? Better yet, are there modifiers that can be used with "sv_cmd radarmap" to make it include the entire map and not just most of it?
