New Terradome 3 terrain?

Couldn't find any documentation on this. Does anyone know how to make new 'terrain morphs' for Terradome 3?
(Essentially, what I would really love to do is create a height map image in something like photoshop, and then use that in TD3. But I am sure thats not how everything works. So the follow on question is once a morph is made for TD3, how can I export it to a heightmap? Or, put another way, how can I get a useful image out of TD3 to then photoshop around on for UltraScatter maps?)
Thanks in advance for what I am sure will be a long explanation!

Boy, those are some good questions! I'll be watching here for answers.
You need a tool that edits geometry by moving the verticies around (Hexagon, Carrara, Blender, etc.) and then loading the morph in DAZ Studio using morph loader.
