That’s what I was afraid of, Dan!
Another option is to make one big comp and put the different color versions in order … and have the color picker vary over time … but then I have the issue of splitting that up into multiple render items.
There used to be a script by Jeff Almasol called “rd_RenderLayers” — but I cannot find it anywhere.
And https://www.redefinery.com/ seems to be down.
Is there an alternative? Was it free? Does someone have a copy? Or any way to split up one comp into multiple output files, by layer or marker, or something?
