Hi Wunkolo!
Thanks for you nice job on making PixMap After Effects Plugin! I'm using PixMap and making templates and selling on several stock marketplaces. So people will download your plugin more.
I have encountered a crash error when working at 4K resolution with PixMap. If happens if I apply Curves just after PixMap and layer mode is overlay. Solved by making layer precomp and applying PixMap as single effect on inner layer.
Hope it helps ;)
Regards.
