Uncaught TypeError: Cannot read property 'x' of undefined in three.js line 468 -


this first time attempting import obj three.js , use it. attempting use object loader included in 3 master build.

the issue seems in how object file loads, errors being undefined in kind of loop. trouble is, don't know undefined shouldn't be. create obj file used https://developer.cdn.mozilla.net/media/uploads/demos/w/i/wizgrav/f232e401f674086f9aae99b474e27ed0/running-image-triang_1372626220_demo_package/index.html

what doing wrong? first time using three, tried make few changes possible (only files in directory structure).

since object, at: http://geevideoproduction.com/geetop3d.obj
