MacOS version working perfectly - very nicely done, and gives all the options I was wanting plus several extra tweaks - extremely cool. A kaleidoscope option - or maybe just a completely new Kaleidoscope plugin - hint hint ;) - would be an amazing addition. Also maybe some colour/contrast alteration in the feedback loop, but this would be just icing on the cake. Brilliant plugin. Many thanks.
I use this to get something behind my overlays as I stream VR and to maximize FoV I run a more square output with overlays to either side, so the stream is still widescreen. I also use it in camera shots where I have some empty space, for a (I am told) mesmerizing effect where there would otherwise be black void!
Lovely filter that I've at the time of writing has used for about 8 months without issues
