Hi Robert Not sure how relevant to you this is, but as I reported I had the same uniform mat4 array issue on IOS gles2. I've downloaded and linked to the latest trunk just now and that has fixed the problem. Was the issue you mentioned Nvidia specific or OpenGL in general.
I guess it doesn't matter either way, I now have the osganimationhardware example running on my iPod Touch 4th gen. Now to try and make it look pretty :) Cheers Tom PS Only change needed was to attach a fragment shader and change a few variable names, shaders are attached.
