How to change Unit scale for project or for map?


I’m creating an accurate model solar system, and would like to be to work with standard units to make my life easier.

  • Measure Location in Terms of Astronomical Units rather than the default “CM”
  • The Scale Units appear to be unit-less - I can estimate the size scale with radius of sun. But I’d rather be able to define a planet radius in terms of KM.
  • Getting a discrete measure of time - this is more up to me, but knowing more about the frequency of Event Tick would be helpful. Especially for MP/Networking stuff & replication.

I am currently controlling some of these features with UProperties, but I want to change the project units directly so that it’s easier to work with existing blueprint functions.

This is probably obvious somewhere in Project Settings, but I am dumb and can’t find it.
