Thanks for your offer to help. We actually have a Galaxy Nexus but there are some 3D driver issues with it. We are looking into this now.
Has anything been found as to why the GNex dosen't show some 3D models?
I've tested a few examples with my GNex and some work. The sample chameleon is an example of one that works. The Olympic park is an example of one that does not work. I'm trying to set up a 3D model myself and I get the "unsupported" device overlay when using my own GNex.
Are there any solutions? The GNex is my only permanent testing device. I have access to an iPhone4 and iPad2 but not all the time...
