Good day, I want to create something like Space Engine on Unreal Engine 4. I would like to keep the same physics as in space engine, and thanks to the unreal engine 4 graphics. What do you need? In Unreal Engine 4 you can create space on such a scale (every planet has to be modeled in real size). And last question, how to create physics for cosmic bodies? Usually unreal engine 4 grace operates to the floor, and I need every body had their gratu.
