Hello
I am doing a small space game and when the ship/character is around 20000 studs away from the center of the map I start to see visible trembling (probably due to floating point errors?)
Is there a way to improve this, so I bigger map can be used?
I don’t know a ton about the floating point but I’m 80% sure that it is the cause of your issue. You can see it in Roblox games like this. I don’t think that you can do anything to fix it other than making your map smaller.
