In my canyon animation I found something I didn't like after 500 frames, and now I restarted the renderjob after the correction.
But meanwhile I had a little study, what is possible with objects, how to convert from several formats to OBJ, where to get nice objects, and.. and.. and...
I hope you enjoy my playfulness

Part one is a study with death star behind clouds (real object! No postprocessing with photoshop!):

And this one is a test with the two suns of Tatooine:

The terrain is just the default terrain after starting TG3 + many fakestones ... the stones in the right under the platform is a rock population.
And to not to forget -- the objects ( all for non commercial use only):
