Additional uniforms for lighting shaders

[Rastar]

Is there any way to pass additional uniforms to the lighting shaders (directionallight.shader, ...) ? (Provided I have modified the sources and added those uniforms). Which is equivalent to. Is there a way to get a reference to the loaded shaders? I guess when I call Shader::Load() for those shaders I get a separate instance that I then set uniforms on, not the one actually loaded by the render code?

The light shaders are stored in a member of the OpenGL4Camera class:

    class OpenGL4Camera : public OpenGL2Camera
   {
   public:
       Shader* shader_ambient[7];
       Shader* shader_directional[8][2][3];
       Shader* shader_point[8][2][3];
       Shader* shader_spot[8][2][3];

 

The different variations are loaded as needed, and there are 48 possible combinations.

Cool, thanks!

Ummmm, sorry for a silly question, but I can't see the forest for the trees right now... what are those combinations (8*2*3) again? And those 7 for the ambient?

[multisamplemode][shadowmode][lightquality]

[Rastar]

Ahh, OK. And those 7 ambients?

 

By the way, it seems the camera (range, zoom) uniforms aren't passed to the ambient lighting shaders. While that is fine for "ordinary", view-independent ambient terms, I would like to calculate an ambient specular contribution. Would it be possible to at least hand those two to the ambient lighting shaders so I can calculate the view direction vector?

 

Thanks again!
