closeup on the outputs

 i love how pixel composer handles arrays. if you pass an array into most kinds of node, it just runs the node once for every entry in the array and outputs an array in the same order. so you can do a lot of repetitive processing without duplicating flows

 this even applies for the file export node. there being one node for each direction is a convenience for visualization, it is not load-bearing

 the name of the file to be exported is itself a node input
