Hi @Tylru,
I spoke with some of the developers and it looks like attempting to flatten out the world would be very complicated. It likely won’t be part of the plugin in the near future.
I agree that a flat map would certainly simplify development in a lot of areas. We have previously explored planetary gravity, you can read the issue here. In particular, the issue contains links to plugins that can approximate directional gravity in Unreal Engine. A solution like that may work for your use case. If you try it, please let us know how it goes!
