Very beautiful work. Space Engine are more realist
Just, ship's lights (lights, thrusters,...) can emit light on a object close (surface of a planet by example) ?
Also, object can make shadow (by example the Death Star hide the sun and make solar eclipse on the planet) ?
Those are very different features to implement, and will take a lot of work, but I believe Space Engineer intends to do them at some point. Initially, he wasn't willing to do emissive textures (glowing bits on ships/Lava) unless they included environmental splash lighting effects as you described. A number of us whined at him until he did emis textures.
But yes, shadows and deferred lighting are definitely planned, just not necessarily any time soon.
Two other texture-related features I'm waiting patiently for are cube-mapped reflections and alpha-blended transparency. That will allow for things like transparent windows on ships with the stars reflecting on the glass.
Cube maps are already being generated for things like black hole and ship-warp distortion effects, so what remains is mapping them to the geometry of the ships accurately.
Bump map lighting also needs an overhaul, the light is not playing on the bumps accurately at the moment.
That's just a small sample of the loooooooooong list of things Space Engineer has on his to-do list, there are a thousand other things I didn't mention, so you can imagine it may be a while before shadows and splash lighting are implemented, but the wait will be full of awesome new stuff!
