It was great to record the virtual video from another app, like https://www.lightjams.com/spout-recorder.html
i would love to send the shaders into other softwares, like https://www.hypertonal.net/cathodemer/
or e.g. Adobe premiere, which have all support for input and ouput of generated materials via spout. It would be a great addition. Anyways, i think i am drifting away from your main focus ;)
