Export OBJ with materials crashes Blender on import I am having an issue with exporting obj files containing materials. I have created default materials in cycles with no changes other than diffuse color for each mesh in my scene, and I export to obj with materials. It is a basic scene, just a few different meshes with a single default material applied to each.

When I try to reimport the files into blender it freezes and can not import it. I am able to export the obj without the materials selection and everything works however in this case I need  separate material for each object created in Blender to be exported.

Anyone have an idea of what to look at to get the export to work properly?

Thanks
Export the .obj out with no materials (unselect write materials on export). Import the obj into a brand new scene and recreate all the materials.
