very interesting, thanks everyone, and thanks for the tutorial savagebeasty 
1 more thing while im here, with the intent of back engineering and basically copy/pasting code to learn from, where do the blueprint nodes live in the source?
ive only found a few and searching the source by the blueprint name you see in the editor comes up with nothing.
cheers

i agree the visual style of blueprints is not the best for creating easy to follow networks, an option to get rid of all the ‘vista’ style stuff would be great, and probably much more efficient for the engine.
i kinda prefer Reaktor style nodes
(wow my old site needs updating lol)
