I've read the article of .obj completely! Yet, not a single sentence says how to link the smoothing groups with the faces.
But I've asked my docent at school and he told me a way to do it. So should work now.. When I've written the code.
About the singleton, yes I've already changed my framework for that.
So last thing I want to say is kinda off-topic.
I'm starting a journal so you guys can watch my progress!
Feel free to follow my blog.

I'll post Part 1 with some code this night. First I want to be sure everything runs smoothly so I don't show you bad code.
