Python error & example blend file are provided in blender issue

Please attach the used images — without them I can't even get that far.

@UX3D-schmithuesen Please comment original issue on blender tracker, it will take too much time for me to replicate messages here & on blender tracker

But ... This error is linked to animation, you should be able to reproduce without the texture, by removing material

[ghost]

Both very valid points! I will create an account for the blender tracker, but first I will investigate this thing without materials.

@UX3D-schmithuesen
I don't know how we have to handle it:

• Not exporting entire animation
• Ignore this curve, and export other curves that can be exported on same animation

Any thoughts @donmccurdy ?

I think I'd lean toward ignoring this channel but exporting the rest of the animation. If there is some way to report a user-visible warning (per #89) without aborting the export that may be ideal.

Right now, we display a warning on the console (I don't know if that counts as user-visible) and skip that entire animation, but still export the rest of the asset.

Ignore this curve, and export other curves that can be exported on same animation

It sounds very good at first glance and should not even be that hard to implement, but we don't know if the animation will still be useful in the end. I like skipping the entire animation, because even without seeing the warning, the user will notice right away that the animation was not (correctly) exported while just missing piece of an animation might go unnoticed at first.
