This THREE.extend pattern creates misterious issues in V8. Sometimes the methods aren't available for whatever reason. Probably easier to move away of the pattern rather than figuring out what's wong in V8 :/

ObjectLoader/ObjectExporter using matrix instead of position/(rotation|quaternion)/scale. See #3591.

There was no need for the load texture to be static

I haven't tested the problem but it was a bad idea anyways to have start and end have the same referenceObject
