Ah, a really nice piece of work! You definitely pulled out a pretty cool result out of the tutorial
One thing, I'd like to criticize is the material of the asteroids. By default, these rocks have a fairly low polygon-count (which makes them easier to render but on the downside quite edgy or flat in some parts). That's why I recommend using a slightly more aggregated material with a high bump depth. If you have the hardware for it, then you might even want to try out turning on "displacement mapping" (this is quite slow to render but gives you extremely good results).
Thank you! Yes, I agree about the material on the asteroids. I am very new to Vue so I still have a lot to figure out, and I've only just begun to get the hang of things. Thanks for having a look, and thanks very much for the tuto!
Very cool! Those are some ginormous asteroids though, I think for a more realistic picture they should be smaller, more or less the same size, and be a lot smaller on the far side of the planet than when they are close to the camera. But still very neat!!
