Is the gravity still hardcoded for zAxis?

Im a lvl artist, and i wana make a lvl within a sphere, similar to halo.
I found alot of threads cince 2014 about this topic, and still its not an option via blueprints

we are allmost in 2019 and still this is not an option?

Well, reality of things is that UE4 has never been meant to be fully usable through Blueprints. That’s a terribly common misconception among starting developers.

However, there’s a blueprint solution that’s been available since day 1: You can disable default gravity and apply forces to your character on any direction you want simulate gravity towards.

Of course you could make a more efficient solution in C++, and specially using Source. But hey, it would look the part.
