Hi,

    I assume this can be found somewhere in some documents. If you know it
from the top of your head, please let me know.

    I am trying to change one components of a vector:

#declare pt = <0,0,0>;
#declare pt = VRand_On_Sphere(MySeed);
#declare pt.z = pt.z / 2.0;

The third line does not process, saying that  a '=' is expected but a '.' is
found. The docs indicate that it should work. Am I declaring my variable pt
wrong?

Thanks for your help.

bongo
