I have a high-resolution equirectangular world map, that I'd love to use for a cooperative worldbuilding endeavor. Unfortunately, some of the continents just aren't working when I project this onto a globe. What I'm hoping to do is apply a distortion to the map, so that the ploar regions are stretched in order to make the map look "realistic" on a 3D projection. I'm using Photoshop CS6. The Polar Distortion filter didn't quite work, and the Spherical Mapping Projection, which seemed very promising, had no visible effect on the map. Thanks for your help!
