Yeah I settled on a random world, heavily editing it to give it a reasonably plausible look, then mapping it out for real in a whole other program. I'll use my hand-made version to alter the placement of mountains, which is what I'm doing now. The raw FT files give me mountainous shapes to use for reference, and gave me some elevation/temperature data to help inform my hand-made process. It also allows me to measure distances etc. though of course I've changed some of the data since exporting it.
