Great walkthrough! I’m also getting into a project soon like this. But one thing! If I look at the tiling stoneblocks on the ground I can see som jagging effect on them. Do you think I can get away with that if I get a highres sphere? If I use the pictures as cubemaps in a material it looks really good but to big texture files!! I need the small size textures :-P But I really don’t want the Sphere to do wierd jagging stuff :-)
Thanks for sharing!
