spherical world help

This is more of a high level strategy question. i am new to UE. I have a spherical world where gravity is working and i can walk around. But i can’t get the world rotation to work right so it feels like natural. I can’t find official documentation for Set World Rotation, and i am getting some strange results. What would be a good best practice strategy for working with spherical worlds? there are also some strange issue with walking, like back only walks forward for example. Any guidance is appreciated
