Gltf-blender-io: Only one NLA animation exports properly

[kungfooman]

Hi all,

I am trying to export multiple animation clips, but it currently isn't working so far. I don't know if my door.blend has a wrong setup or this needs some fixes in the exporter. For better illustration I made a short video:

If anybody wants to test this, I uploaded door.gltf, door.bin and door.blend here:

https://killtube.org/downloads/khronos/

I am currently using the latest version of the exporter.

I just added a third animation: every animation works
Adding a fourth animation: works aswell

So my current suspection is it fails when there are only two animation clips

Transferring this to the new repository, i've confirmed the bug still appears in glTF-Blender-IO.

@UX3D-nopper I believe this should be kept with a "bug" label. It's not a regression compared to the old exporter, the problem is pre-existing, but it is a bug from an external user's perspective. I would consider "enhancements" to be feature requests instead.

This is maybe link to NLA issue #461

Model appears to be exporting correctly now, @kungfooman could you confirm with the latest Blender 2.8?

@donmccurdy I tested door.gltf and made new animated models to test around and couldn't reproduce this issue. Thanks a lot for everyone involved. 👍
