I have made a very basic animation in Blender (2.79) and I am trying to export it as a GLTF or GLB. I have succesfully installed the gltf exporter and am able to export both gltfs and glbs of unanimated models no problem.
As soon as I add animation and try to export however, I get the following error message
The animation is as about as simple as it could be, I'm just experimenting. Its just the default box that changes location and rotation across 3/4 keyframes.
I am new to Blender so perhaps I am missing a step but my process is as follows: Add box to the scene, add keyframes (LocRot), go to export as I would with a static object, this has the following (default) settings.
I have tried clicking Pushdown on the action sheet as I have seen suggested somewhere but it makes no difference.
Am I missing something? Please let me know if you need any more info in order to advise, I'm happy to share the file or whatever might help.
Thanks for any help,
