Hey everyone, I’m super new to all of this stuff so I hope someone can kinda point me in the right direction!
I want to create a scene with a small ship or satellite orbiting a planet, but I don’t really know how to go about it in several ways. First would be the planetary atmosphere, I really don’t know how to create such an effect!
Then the actual size of the planet, the ship would be in a low orbit and I’d want the planet to be real scale, but is such a thing even possible? How to manage something like this where you have such a huge object? And then as the ship is constantly orbiting the planet, it would probably be easier to just rotate the planet, starfield and sun around the ship, but I also don’t really know!
I don’t really have a purpose for doing this, it’s just something I’d really like to do, any ideas would be appreciated!
Why not try it and see what happens? If you really don’t know where to even begin with the first step then my suggestion is to just start out with something easier.
For starters I wouldn’t do this in a 1:1 scale, as the UE4 engine is using 32-bit floating-point calculations for positions of objects, which basically means things will start to jitter about after something like 8km away from 0. I’d start with everything scaled down by like… 100/1000/10000 depending on the size of the spaceship you’ll be using. alternatively, you can set up a skybox that references a scene capture texture of a smaller planet sphere somewhere hidden from view, so that the planet is rendered as part of the skybox and so doesnt need to be a complete sphere, but can still rotate etc. that way you wont run in to any jitteryness and can still work at 1:1.
