Nodes: When to Use UpdateBefore(), Update(), or UpdateAfter()

[cmhhelgeson]

I’m trying to more accurately understand how to extend Nodes and how the update loop within nodes works, particularly the differences and usage of the updateBefore(), update(), and updateAfter() callbacks. I have a remedial understanding of the utility of updateBefore() in post-processing passes, where it seems to mainly be useful for updating values that are used in setup before each render call ( for example, updating this.textureNode before a call to quadMesh.render() such that the textureNode value used in the blur pass is different each time). However, I feel like my lack of a broader understanding of when to use each is impeding my understanding of the code. Perhaps this question is too broad and unfocused to invoke an answer, but if any general clarity could be provided on how to use each, it would be much appreciated.
