    Since glTF format specs have no support for LOD groups, would it be possible for you to add an option to import LODs from separate glTF files using specific file name convention?
    Good idea, I'll look into that.

      Anything that screws over the monopoly of the extremely rigid and limited FBX format of big brother Autodesk is fine by me.

        One issue with glTF is that skin bindings only allow a maximum of four joints per vertex. This is meant to allow instant loading for glTF meshes on mobile gpus, but it's going to be a bit of a pain for UE hero assets.

          It's exciting to see the adoption of a hopefully more open transfer format.

          Is there a place to track progress on this glTF import functionality? Like on the roadmap?

              Good point. JOINTS_0 and WEIGHTS_0 are part of the standard, each holding 4 values. We could use non-standard JOINTS_1 and WEIGHTS_1 to add four more. This should let us work up to Unreal Engine's limits.

                I'll look at that soon & make sure re-import works.

                  DangerCobraM when do think skeletal mesh import will be supported by unreal? - This would solve so many problems for me as a blender user. I just want to be able to simply skeletal retarget my characters to the mannequin

                    I just released a preview version of glTF for UE4.
                    It supports to import the skeletal mesh and the animation sequence. You can download it from https://c4gio.itch.io/gltf-for-ue4. And it is free and an open-source project in https://github.com/code4game/glTFForUE4.

                      By chance, have you tested it with https://github.com/KhronosGroup/glTF-Blender-Exporter exporter ?

                        Sorry, I have not tested the glTF-Blender-Exporter.

                          Hmm.. But how do you export glTF from Blender in order to test your UE4 import plugin ?

                            DangerCobraM Given that it looks like glTF will become Unreal's preferred option to FBX, will there also be an export scene to glTF function?

                              ditto--are you supposed to use https://github.com/KhronosGroup/glTF-Blender-Exporter , to export and test plugin,I presume so, clarification ?

                                That's what I figured, since it's "official" glTF exporter for Blender.
