Hey All,
I'm really excited about the new Away3d 4.0 library, however I've been
running into a lot of trouble loading even the simplest objects.
Embedding objects leads to a missing .mtl file even when I trace
baseUri + mtlurl in OBJParser and it's correct. So I've gone with
loading external assets (which I prefer anyways). I've searched far
and wide on this group to try to find an answer but I'm stuck so here
I am. Here's all the relevant files and the stack with traces at
specific points, any help is greatly appreciated.

I'm stuck because it's referencing an index in _objects however
between when the instance of the object is created and when an index
is referenced in it nothing in between pushes any values to it so I'm
confused how this could possibly work in any instance.
Any help is greatly appreciated.
Thanks,
Mike
