That's what I thought but it was not working. There was a silly mistake in my osg code, I was reusing texture2 instead of texture3 in the last image assignment (as you can see in my first message). That's fixed now. My problem is tha I have a fixed possition in world coordinates (LightPosition) as a Uniform parameter. At the time of passing it to the vertex shader, apparently it is seen as fixed in screen coordinates. If I move the view, the scene moves but not the effect of the shader. How should I convert the vertex coordinate? I know this is maybe a faq but as I told, it's my first shader experiment, and I can't make it work. I will highly appreciate any help.
