Hello,
I am very new to GLSL and trying to implement a simple per-pixel lighting. I found a lot of resources on the internet that even propose pixel shader and fragment shader code for this, but something is always wrong: the "default" pixel and fragment shader code is missing it seems (I get pixels that are individually lit, but everything is very dark, only one light supported, colors are strange). So it seems that a shader is just a piece of a puzzle, and should be combined with other components. But how? Or where can I find the code for a per pixel lighting shader, that supports my 8 lights and will basically render my scene as previously (except for nicer per-pixel lighting)?
Is it that difficult to have a simple per-pixel shading in openGL?
