Hi, not 100% sure, but I don't think you can use one single GLSL for multiple objects. You should use one GLSL applied to each objects. In this way, each objects will apply the same GLSL with his textures and 3D positionning and lighting information. And if you need to act on full scene, you should add one GLSL at the end of your pipeline, playing on your 2D final rendering.
