Updates:
I forgot to click on the change view to render camera button so I accidentally made a random close up cliff render... and it's not bad! haha
Also fixed the Titan scene. Added some proper ground texture, orangish sand-dust on top of everything, fixed the stone sizes and distribution, no reflections, better displacement on the rocks.
Not sure if liquid methane looks like this but oh well...
Also a render with the new cliff textures(the over tweaked ) The detail noise displacement is a bit too strong, the clouds could be better, so it's not a very good pic.
update: I added the first titan render, for some reason the atmosphere didn't render properly (at least you can see there's a moon in the background)
