Question How do I get around the floating point limit for unity?

I need to have a large world, and I am planning on incorporating multiplayer into my game, so moving everything except the player won't work. The limit I've found is 100,000.00, but that only goes to 2 decimal places, and a 200,000 unit cube is too small. I could shrink the size of everything, but that would require more decimal places than 2, which means going back, which means we're back where we started. Does anyone know of a workaround for this?

 

This isn't a limit in unity. It's a limit of floating point numbers in general.

Floating origin does not work, because I want to have multiplayer

 

You can build a large open world multiplayer game using a floating origin. You may need to build your own custom networking solution to do it well, but it can definitely be done.

 

How would I go about that?

 

Have the client maintain its own Origin-TRSMatrix. Then do everything relative to that.
There'll be some slight 'errors' but only on objects that are far away from the client's origin, so that shouldn't really matter.
