While on my research on the glTF format, I managed to find out that there was a glTF importer plugin someone made on github. It looks like it’s outdated a little, and I believe it’s only static meshes at the moment. But it looks like someone wrote a plugin to be able to take glTF meshes in unreal about a year ago.
Not sure how well this might work now considering it’s been a year, but at least we can import stuff using this if someone recompiles it for later engine versions like 4.16 or 4.17. This seems to be very promising, so I’m hoping that this stuff goes further.
