I've spent the last 4 days learning how to build stuff in Unreal Engine 4. I'm feeling confident enough right now that I think that if I had a good starting point, kind of like how Unreal 3 has Sonic GDK, I could make something interesting. Not a full game quite yet, but I'd like to play around with things. Like I said, Unreal 3 has Sonic GDK. Are there any decent setups for Unreal 4 that I can play with?
Nothing decent so far. It's just that as of yet, not many have a good enough plan to make a 3D Sonic framework in UE4 without falling into the same traps HedgePhysics and SonicGDK did. EDIT: Sonic Unreal Worlds is pretty decent, probably your best bet at this point in time.
