I have a workaround: using image.reload() after loading

This is a known limitation of Blender (not part of the exporter): You can't apply modifier on mesh with shapekeys (even manually).
This is the current behaviour for FBX export too.

Closing this ticket as this is a duplicate of an issue already open in upstream repository.

Your armature object has not default rotation / scale. It's always a bad idea in Blender
Seems applying rotation/scale before exporting solved (at least partially) the problem.

I received the file.
Discussion will continue on upstream repository: https://github.com/KhronosGroup/glTF-Blender-IO/issues/667

You can send me a link to download you blend file via email (contact<AROBASE><FIRSTNAME><NAME><DOTCOM>) or via twitter (@julienduroure) if you prefer

Hello,
Probably more a feature request than a bug, because this is the global behaviour of blender to work like that. Closing this, not really linked to glTF specifically.
This needs to be discussed with other developers if some workaround are possible or not.

Seems to be a limitation of Blender. Same way you can't apply a modifier when there are some shapekeys, you can't export it this way.
(Note: this is also the behaviour of fbx export).

@Omar Emara (OmarSquircleArt) : the wrapper is used for importing/exporting formats that support material setups (currently used for FBX, OBJ, 3DS)

I committed the proposed fix.
If more speed is needed, we will have to check in API if something is possible

Note : I created an issue on the upstream repository : https://github.com/KhronosGroup/glTF-Blender-IO/issues/626

Note: glTF import / export addon development is here : https://github.com/KhronosGroup/glTF-Blender-IO
There are already some tests automatically done at every commit on github by circle CI

Hello,
Regarding collection issue ;
I cannot reproduce with lastest build. Can you please test with last build from https://builder.blender.org/download/

More than a week without any answer from user, so closing this ticket. Don't hesitate to reply if you want.

This is now fixed after commit 2c08beb9690c

Please provide a .blend file to reproduce the issue

@Philipp Oeser (lichtwerk) Thanks for the link, I definitively have a deeper look into it

I can confirm.

I can confirm the bug.
Seems that you are trying to export a mesh with a shader where the texture file is not existing (or you didn't provide it).
Maybe this PR will help : https://github.com/KhronosGroup/glTF-Blender-IO/pull/559

Note: We have a texture node, but you didn't define a texture file or internal image in that node ... So this can't work. We are going to add an error message in that case

I just pushed a fix about applying modifiers

Hello,
The repo should be up to date, thanks for reporting this issues it let me find an issue in the code that merge code. I will fix it upstream after the weekend.
