Amazingly there is VERY LITTLE information on how to write a FFGL plug that works in Resolume. You're pretty much on your own.
Also if you look around for 64bitFFGL plugs you will come across a lot of 404 notices. There's almost nothing useful that works for Resolume, it's basically a graveyard. I think we need to get a how-to up and running, make it attractive, simple, demo plugs etc etc.
