    Hi,

    I want to extract the correct colors of a rendered line. The color buffer in ExecuteLine though is NOT the same as the actually rendered line.

    I tried using the RayFilter on the line but the Filter doesn´t seem to work (or at least I cannot get it to work).

    So is there ANY way to retrieve the correct colors in ExecuteLine?

    Here is how I get the color:
    ------------------------------

    LONG mul   = pp->aa ? 4:1;  
    Real *col = pp->col+pp->left*mul*pp->comp;  
    [...]  
    for (x=pp->left; x<=pp->right; x++)  
    {  
         LONG r=0,g=0,b=0;  
         for (i=0; i<mul; i++, col+=pp->comp)  
         {  
         r+=col[0]*256;  
         g+=col[1]*256;  
         b+=col[2]*256;  
         }  
    }
    

    --------------------
    The color is then Vector(r/mul,g/mul,b/mul). But when I compare the line with the line of the rendered image, they differ.

    :-(

    Anybody any idea how to solve that?
    Thx i.a.

    As far as I know there's no way to exactly replicate the output of the render from the ExecuteLine() data, since it's filtered within C4D afterwards.

    Hmm, That´s a pity. How is one supposed to work with colors in ExecuteLine if they are not "correct"?!

    Well, let´s hope for a future release to return the final colors.

    Thanks anyway!
