Hi I just downloaded the addon and tried it on blender 4.1 and 4,2

I am getting only black images. Do I have to use an older blender version to make it run or is there any other reason why its only rendering black images? 

Maybe it helps also to know that I disabled the palette function. 

So would be nice to make it possible to run it for the latest blender version if this is the issue.

Nevermind its working. I had to add the viewer in the compositing!

Glad to hear it's working for you now! Apologies about the late reply, I was in the midst of a power outage at the time this got posted.
