Hi,
I want to place tree rows along the z axis. Trees should be rotated
randomly, but each tree pair (trees that are located in Pos and 0-Pos)
should have same amount of rotation.

Currently following code doesn't do that; All of the trees are rotated with
equal values. My guess is that for some reason RdmC isn't updated when it's
called by RA.

Question: Why this xxxxxxx code doesn't work?

Sorry if I offended anyone. I guess i'm a little bit tired. I'm writing this
at 3.21 AM and should be at work by 8.00.
Hmm, maybe I should join POVoholics Anonymous :) :) Anyway here's the code:

#include "rand.inc"

#while(A<Loop)

#declare RP=VRand_In_Box(<-1,4.9,-5>,<1,5,-5> , RdmA);
#declare Pos=trace(Lightside, <RP.x,100,RP.z>,<0,-1,0>,Norm);

#declare RA=RdmC;

object{ TREE scale 0.12 rotate y*360*RA translate Pos}
object{ TREE2 scale 0.12 rotate y*360*RA translate <Pos.x, Pos.y, 0-Pos.z>}


#declare A=A+1;
#end

Thanks
Janne

RdmC is the *seed* of a random number stream. To get a random number
from that stream you should write

#declare RA=rand(RdmC);
