Like a planet-planet sized stuff? Yeah, no, I don’t think so. This would be pretty much faked everywhere bar NASA’s Mars mission. I read their paper on using ISS propulsion module last year. 90%+ went over my head, ofc. What did stick made me realise the whole thing stays in orbit due to brute-force multiple redundancy error correcting controllers. And they do not even need to worry about frame-time…
There are improvements coming to double precision for large worlds and Chaos is very actively being worked on. Chances are what you’re after can be achieved or you can get closer. Providing I understand correctly what is needed here, I can be of no help, sadly.
I still have flashback after trying to spin a 4km disc in UE4 and have a Pawn Movement Comp respect that. Folks have issues rolling a ball on a flat surface without it getting all bumpy.
