While working on a project I came across a limitation of the Resolume's LED fixtures. There is no support for non-rectangular configurations. I have a Adafruit NeoPixelr LED ring that was just not going map properly out of the box.
So I cam up with a solution in After Effects that converts a circular animation to a linear graph that can be easily mapped in Resolume. Until circular fixtures are natively support in Arena, this is the best solution I could come up with. I hope you find it useful. See video below for detail:
