UE4 large worlds (double precision coordinates)

Hello,

I’m new to UE4. I’ve been reading some answers here about double precision coordinates conversion.
I’m looking for an engine that could handle large worlds (100x100kms and up, also 30+ kms of height), for an fps/sim multiplayer hobby project. Visual fidelity would be secondary.

I’ve been reading about some technologies that can extend the 8x8km practical limits others mentioned, like:

  • World Composition: here, I’m not sure how would tiles load as flying with a jet and how the view distance or far clipping would look like
  • fp32 on client side, fp64 on the server side: anyone has a working example about this?
  • Level streming and origin rebase will not work in multiplayer
  • Scaling down will have issues with e.g. physics as well

How good is UE4 as a vehicle simulation platform?

If some of you happen to know any working forks (or plans on UE roadmap) to support fp64 coordiantes and spaces, possibly on the editor side as well, please let me know.

Thanks in advance!

Cheers
