Update Nov 9 2019
this is trappistplanets from discord
i have a REAL height map (DEM) of europa
(filled missing poles)
its kinda useless but i made a semifictional one
from that dem and your europa texture
there is also a real callisto DEM too
and i made a semifictional map from that and kexitt's fictional data
and there are real height maps for the uranian moons other then umbriel and oberon https://repository.hou.usra.edu/handle/20.500.11753/1687
and i made a feb 9 2021 cloud map
and i found a real enceladus height map (you can convert this to a norm map for a 3rd version of PE
no i am not telling you to add these, but these are just here if you want to include any of them into a 3rd version of ProjectEchoes
What's the difference between Project Celestia Echoes, Celestia Origin, and Space Engine? What do the Celestia Echoes and Celestia Origins textures look like in Space Engine? Which one do you think is better?
Good luck in your future endeavors,
Just know that if you ever feel like taking a break from doing space stuff you're free to do so, I'm sure the community will understand.
