In my implementation, I create several clones of
a set of one pfDCS and one pfGeode node (the geode is
a child of the dcs node).
I have defined textures for the geode node.
I also ensure that I preload the textures into
hardware texture memory. (on a octane with 4MB TRAM).

I had thought that only one copy of the texture would be
used for all the instances of cloning (as the geode is actually shared
between all the nodes). But when I check the
statistics, I find that with every instance of cloning,
the number of textures increases by 1 and soon they can no longer fit
into the TRAM and so start swapping a lot.

SO, can somone please explain how I can get them to all share the same
texture without creating copies of it?

Thanks
Rama
