OMFG I FOUND IT I FOUND IT!!! IT IS POSSIBLE!!! Someone made a plugin for it… that is $250 T.T but hey, it’s possible. They don’t even need to do world origin rebasing, they simply changed to 64 bit coordinates!!!
■■■■, this looks a lot more complicated than I imagined, but that, THAT is exactly what I want. I’m not sure if I’m ready to shell out that kinda money yet, but wow it’s tempting. Maybe, after I’m done with everything else making a game fun on a flat planet with land/sky/water vehicles, I’ll explore if I can accomplish this, or just bite the bullet and buy it. I am sticking with Unreal Engine, no more temptations from Unity.
