[osg-users] How to Preserve FBX baked in textures when running running hardware skinning

I run skinning.vert on my fbx model which has rigging. Ive attached the shader program as in the osg hardware animation example. I have a texture that accompanies the hand model in the FBX file that I export from 3Ds max. If I don't attach the shader program the hand models show up with the
