Switching images in COPs


Recommended Posts

Hi there. I have 6 images of various sizes pulled into a switch node in a COP network.


I want to change the input index value of the switch based on the $F frame number. With the idea of using a ROP to render out a different result per frame. I can manually scrub the switch, but when I put in the $F expression its not happy.


The issue is when I put $F -1 in the input index channel, I get an error saying not all the images are the same size or format or plane etc, and to possibly use a blendCOP.


Is there anyway around this?, or another way to achieve animating in the switch index of a bunch of random images.


Formatting all the images to be the same dimensions will likely break what I'm actually doing.


Thanks for your help.
