Hello James,
thank you very much for the detailed inormation.
Yes.. i already checked that description page.. i think its very cool
because it is nery nicely explained how to setup things.
This could be definately an tutorial on ldraw.org because everything sounded
evry easy to me ;).
If you have the chance to render another movie i would be very happy to hear
more details about the clusters speed and what machines its using exactly.
Play well
Carsten
