Is there a way to display a progress bar in Blender’s info bar during scene export?
When we’re exporting game assets at the studio, Blender sometimes freezes for a minute or more. It’s bothering our animators quite a bit. It’d be nice to at least communicate to them that Blender hasn’t crashed, and the export is at X percent.
We’re using a custom script that runs bpy.ops.export_scene.fbx.
‘INVOKE_DEFAULT’ doesn’t seem to work here.
Well, I guess there really isn’t a way then. That surprises me, but we’ll just have to live with it then. 
You can tell your animators to open up a console window before exporting.
The window is updated with what is being currently exported.
A graphical bar would be possible and somewhat easily implementable, but it ends up adding loading/io overhead on an already pretty hefty operation.
It’s likely your animators would end up hating the extra delay even more than just waiting… either way it’s good food for though.
I see. Thank you for your advice.
For now, I’ll simply stick to briefing animators about this issue, and that’ll have to do.
