No, unfortunately not. For the picture, I've carefully placed the ship and the astronaut such that they look like they stand on the ground, but the ground is not really solid, so you can still move through it.this is looking great, is the ground 'solid' i can see you've parked your ship on it so i guess so.
Are you planning on adding any objects like rocks, or trees on earth? If you need some objects to test with shoot me a pm with your email address.
That's more like a long-term plan. I've already decided for myself that I'm not going to do atmospheric rendering and clouds (or maybe only in the demo program), and that collision detection (which is needed for 'solid' ground) also needs to be done by external code. First, I'm going to focus on the surface tiles, and then maybe on objects.
I wonder how difficult it would be to use Artlav's collision detection code with OrbiterProcTer instead of Orulex. I think that collision detection with a continuously changing terrain is quite a challenge anyway.
