I have implemented what I call PixelPlane capability into HLS.
You identify the number of pixels you want to control. It is up to you to set the Universe Number and Channel number to match your hardware.
Nutcracker will export a HLS formatted file that can be then positioned within your sequence.
In the Sequence Editor - you see only a Single Channel that represents your PixelPlane so you are not burdened with a lot of channels.
HLS will only output your PixelPlane data - which means it is not viewable in Preview Mode.
If anyone is interested - let me know and I will make a video on how to use the feature.
