So I'm currently making an Unturned Map project, which is planned to be an exact replica of Capital Wasteland. I tried using the real Washington DC heightmap for it, but it's not very accurate and it's super flat (unlike the CW), which is understandable. So I tried searching it on google for a Capital Wasteland heightmap but all I could fine was the Mojave Wasteland heightmap, So do any of you guys happen to have the CW heightmap?
