Being new at all this could literally take weeks to figure out the problem, thank you it brings up the camera for that example, tried implementing this change to other examples for the 2.0 but didn't work, it works with processing 1.5 fine. 

But my problem is that I am trying to integrate an OBJloader library with Nyartoolkit so the marker displays the 3D image, i figured out how to get the obj. file to display with textures using the PShape function, but i realised that PShape is only for processing 2.0 and not 1.5. Is there any way to make this work or will this indefinitely be incompatible do u think? It's for a university project so i am starting to get really stressed that it might be impossible to work.

Any advice on this? I've been looking for a solution for a week now and still no luck at the moment.
