When using the latest blender rc’s (2.74 test release as well as daily builds), this error pops up when trying to import obj’s that have only edges and verts (no faces) to blender:
init.py line 144, in execute
return import_obj.load(self, context, **keywords)
import_obj.py line 960, in load
face_vert_loc_indices, _1, _2, _3, _4, _5 = face
ValueError: too many values to unpack (expected 6)
This error doesn’t occur when the ‘Lines’ options is unchecked in blender import settings - the object will import without throwing errors, but it will not be connected with edges, just a bunch of points.
To test, delete “faces only” from a default cube in blender, export as an obj, and then import back into blender.
Anyone know of a workaround?
