well it was just gimp ... ... to make the earth shader I....
- created a new document using the build in "land" script that pretty much takes random cloudy noise and puts a gradiant on diffrent parts depending on brightness
- then for the gradiant I picked the thin blue line one
- then I made it seamless (using "make seemless" filter)
- then I rendered a grid using the "render grid" filter
- made it blue
- then I merged the line layers
- then duplicated that ... and added a "tileable blur" to add a glowyness to it
- on a new layer ... using the paintbrush tool I made some red lines (shift click))
- and by making some circle selections and using "edit-> stroke selection" I put some small red circles/dots on the map
- put lables near the dots for other maps that are on the same planet in the xoniverse (like lightspeed and solarium)
- then save as a tga ... and use the same shader file as the glowy things on the bottom of space elevator
see ... just gimp ... not that difficult
:: edit ... I forgot ... I also use a layer mask on the entire thing to fade out the top and bottom ... so you cant see the texture messiness that goes on there when you map it to a sphere
