I've been trying to rely on forums less, but yet here I am to pester you.
Problem this time I've had for about a week. I've been experimenting with a
variety of different codes and having no change in success. The title says
it all.
I abandoned my previous project as I discovered someone else had a very
similiar idea, and had much more done. So starting from scratch again.
First I would like to point out that it's far from done. I don't even know
where I should create the VBO's, yet alone draw them. So here you go.
My loading screen activity:

To summarize that, it loads in all models and adds them to an array
successfully. Problem is not there. How would I go about actually creating
the VBO's and implementing them into an OpenGL ES 1 renderer?
Help greatly appreciated!
