Error exporting animation as GLTF file 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,
Here's how I got it to work:

1) Upgrade to the latest Blender 2.8.1

2) Go to export panel:

Export -&gt; glTF -&gt; Presets


3) Set the options:

Transform -&gt; +Y Up
Animations -&gt; Always sample animations


4) Test your exported animation in a viewer:
