Thanks for this tool.
Would you consider posting the code for this on GitHub so it can be modified? I have a few ideas for this, like generating textures from the command line, and randomization.
I think I can do that. I removed the planet generation feature from my game "The Fermi Paradox" so there wont be any conflicts and I could put it on GitHub. It would be awesome others play around with the code. Honestly I have not so much experience with Git collaboration, but I would like to try this with the Planet Generator, because there are still people interested in it. I put it into my to-do list and hope I have time for it soon.
