OK I'm concerned that Unity with it's 32 bit floating point precision and Physics, is limited to small worlds. I have argued the addition of 64 bit precision to the engine on a separate thread. But this has bogged down to different binary camps 32/64 bit. So how about we have a Massive World or Space Challenge. Can you create a Massive World or Space using Unity, that a player can traverse quickly, ideally using a vehicle and have working game physics. So what scale would be massive, well solar system spanning, planet spanning or just 100km² or greater. If you don't think it can be done in Unity check out Kerbal Space Program and Homeworld: Deserts of Kharahk. There are basically two ways to make a massive world, you can tile it and shift the players origin or adopt a higher precision system to simulate your world. Ideal game themes for the challenge, Racing, Flight, Vehicular Combat, Space. Think of those massive theme setting scenes in films that show an entire world that you want to explore. The idea is to stretch what we can do with Unity and better understand it's limitations and share our experinces, what works and what does not. And if you have an asset store system that can do Massive worlds, please show it off by taking on the challenge. The Title of Unity Massive World champion 2016 can be voted on by the community. Have Fun.
