Hi JS, Thanks so much for your detailed explanations. I get your thinking. I have known same think but I didn't sure very well. My last question is, I have declared; uniform sampler2D diffuseTexture; in my fragment shader, although I didn't bind it to osg::Uniform in my main application, I can sample my texture from my shader in Unit 0. Do you think it is weird or not? You have said that; I only need to bind my uniform sampler2d variable in my application to set to related stateset. I didn't set to stateset too, but I get the unit 0 texture value from shader and can see my model textured.
Thanks again.
