gltf_auto_export v0.13, does not export animated objects correctly

[kaosat-dev]

@janhohenheim this is for the issue that you found with the export of the animated objects Btw, I am experiencing some very weird things:

• If I export the root object using the standard gltf exporter (not auto), I also end up with an empty gltf file ???
• Exporting the whole collection (whether the blueprint or an instance), I get a correct gltf file.

@kaosat-dev can confirm. I don't know why, but the fox is only exported when you right click the "Fox" collection and "select Objects" which results in this gltf test.zip which can be opened in https://gltf-viewer.donmccurdy.com/ successfully.

Using only the "root", I also get an empty gltf.

@janhohenheim Thanks for the double check! I am not 100% sure it is related, I need to double check the Blender 4.0 release notes. It might have worked until now because of the hack-ish way I was doing things before. (not the first time that a hack works better than clean code in Blender ...)

So this issue is driving me nuts: the best I managed so far is this:

• I can manage to have both the skeleton & the mesh exported
• Regardless of how I try to do the internal "cloning" of the animated mesh, animations are always missing, despite the fact that in python I can see the animation data ??!

Sorry for the inconvenience, once again !

Well, I just started a first person project, so until I need moving NPCs I'm fine, hehe

[kaosat-dev]

@janhohenheim haha, all is good then ;) Joke's on me, I forgot to enable exporting animation in my automated tests :D I will double check things, but I think it should be solved, PR very soon

@janhohenheim the fix & related tests are up ..however, there is something weird going on:

• the animated fox as exported from my own blend file looks like this :
• when exporting the version from Foxtrot it looks like this: When I import (Blender file append) your version into a test blend file, I get the same weird results. However, I have tried multiple gltf files I found on sketchfab, And I could not reproduce the weirdness: (all of these have been re-exported using gltf_auto_export, this branch:)

Tempted to still merge this PR (as it seems to work in all cases I could muster except for Foxtrot's version of the fox), but if you have some time & any ideas on what is going on, would love to get your feedback

[janhohenheim]

Wow that looks... interesting. Poor fox! Yeah, if it works with everything else it should be good enough for a merge. I'll just reimport the fox. Is it maybe a scaling issue? Have you tried "Object mode -> CTRL A -> apply all transforms" beforehand?

[kaosat-dev]

Poor fox indeed:D Also , bingo , scaling issue: it seems both our versions have scaling problems , applying transforms does solve some of it but not quite as you can see below :) I would still consider it a "not exporter" issue ? (yes, for once I am sorta lazy :D )

[janhohenheim]

Haha, great! Yeah, not an exporter issue :)
