This worked fine in RC5 (or maybe it was 4) but does not work in RC6. Can
anyone tell me why or better yet, how to achieve the same result? I'm using
the function as a pigment on a plane...
Thanks much,
D.

function { (PF3(x*clock,y*clock*1.1,z*clock*.9))^((PF2(x,y,z).red)*1-clock)}



(if interested):

 #declare PF2 = function
    {E*sin(A*sin(I*x*(1-1)) + B*cos(J*y))
              + F*cos(C*cos(K*x) + D*sin(L*y*1))  }

   #declare PF3 = function
    {E*tan(A*sin(I*x) + B*sin(J*y))
              + F*sin(C*cos(K*x) + D*cos(L*y*1) ) }
