Three.js: Blender Exporter Crashes trying to export scene

Description of the problem

Blender Exporter Fails to produce a .json file and throws an error that could be improved with clarity

Traceback (most recent call last):
  File "/Users/kev/Library/Application Support/Blender/2.78/scripts/addons/io_three/__init__.py", line 812, in execute
    exporter.export_scene(filepath, settings)

KeyError: 'repeat'

Is there any way to get better logging from this?

Do you mind sharing the .blend?

Seems to be an issue with textures. If I don't export textures it completes successfully.

I think 96f9ed2d058642ee88bdc32c8d9473203ef8e8df fixed that. Do you mind trying the latest?

I think we can close this issue, see https://github.com/mrdoob/three.js/issues/10928#issuecomment-286774322
