Wanted to know if there is a reason why something like Karl Henkel both his "3D Object to Layer" and "Layer to 3D Object" nodes are not included in the stock nodes ?
Using it quite often to bypass some limitations (Use Copy 3D Object with Material with layers), having scene based compositions not having to select different Z-axis to blend nicely etc.
Once "Allow custom node paths" will be implemented it won't be really a problem anymore, but until then, it's sometimes complicated to share compositions with custom nodes.
This is a simple imitation of https://www.instagram.com/p/BosaT7iAJwA/. (This composition uses gradient noise for the line's path, instead of the original's second-order pendulum.)
Each frame, this composition renders the scene many times, moving the camera's location slightly each time, then blends all those images together to produce the output image.
This is one way to simulate camera blur / lens blur / depth of field.
