Aaaaah THANK YOU ! I'm "aware" of the PCOpen+PcFilter to gather infos based on distance. I also use the PrimUV a bit and XYZ+PrimUV for location things.
I'd be curious on the For Loop Vop, if you have any pictures :/ Sorry to ask. It's a shame there's no tutorial or phylosophycal explanations of these basic loops ... It's like if everybody was a natural born coder...
