More Shader Layers

[averagehat]

'cause you can never have enough.

Note that this complicates things because there are many ways to combine and order shaders.

So it requires defining a directed acyclic graph; presumably multiple ones, or one you can edit. One way is to have a menu listing some pre-defined graphs. You could represent these graphs in a JSON file. The nodes on this graph could be had-coded paths to shaders, or a shader layer number. The latter would allow a user to swap out and add shaders on the fly without having to edit a configuration.

You'd want this graph to be able to represent where the preview or sample video input will go, if it exists as well; not sure how you would represent 'a backup plan' if that preview/sample isn't there.

(note that if you wanted, you could add nodes to the graph other than shaders, like feedback, 3d objects, playback sequences, Midi CC, etc.)
