Hey, how do you use Opentoonz with UE4? If I were doing 2d animation within the software, what would be the best way to get it into engine? I draw each frame by hand, scan it into Gimp, ink it and paint it there, then set up the animation in Opentoonz. I am not sure which animation files UE4 accepts, as I only have experience with sprite sheets. For my workflow, though, sprite sheets would be very inconvenient.
