Hello Barry,

to understand the nodefile it is neccesary to think in positions of your objects. Then select the matching positions of your objects with the idxSelect nodes -controlled with the Quartz node.
Thats all.

I will have a look to your idea and try to understand it, but not today, it's late in the evening and I had some beer while watching TV(Soccer - Worldchampionship qualifing:-).

So have a nice evening
Karsten
