    Hi,

    How do I use AllocRayLight?
    Here a little code sample from the Output function of my shader.

      
    BaseObject* op = cd->vd->op->link;  
    if(!op) return Vector(1.0, 0.0, 0.0);  
      
    RayLight *light = AllocRayLight(op);  
    if(!light) return Vector(0.0, 1.0, 0.0);  
    

    What Object must I pass to AllocRaylight? Where is the right point to run this function, the manual is a bit vague about it. I like to add some own lights in my shader and to calculate the illumination thru my own IlliminationModel.

    thanks in advance,

    Matthias

    I believe the object you give to AllocRayLight() is used to fill in values. So it needs to be a light object.

    thanks Mikael, I solved the problem by writing my own
    lighting system.
