I am planning on exporting my models to the Godot game engine. I’m still figuring out how to do it, and as Godot 3 will come out soon, I want to learn as much as I can about exporting my meshes. Godot seems to be left handed as well. I don’t know much else yet.
Good luck figuring that out

I’m planning to export my models to Unity 3D so I won’t have any problems
