So, to really help you any further, we'd probably need to see the model and how it renders on desktop and GLES2. Otherwise, it's too non-specific of a question to have a singular answer. Remember, desktop FFP GL has a LOT of features, many of which may not be emulated by whatever shader you've att

Hi Chrisitan, Hi, I am not sure if the original poster is aware of this, the osgvertexattributes osg sample code is able to generate shaders from fixed function pipeline state sets in the scene graph and applies these shaders to the geometry. http://trac.openscenegraph.org/projects/osg//brow
