Thank you for your quick reply, Avi!
I think undertand that much already, I've aldready downloaded the zip and I was looking at the bat-file yersterday so I've seen "set outputFormat=png". What I don't understand is how I can set 16-bit or if I want alpha or not like in the regular pop-up for CIE.
Backstory is that I render to CXR because I have a LUT on in VFB that I don't want to be burned into my TIFF. And I don't dare render to TIFF directly in case I forget to turn it off.
But it takes ages to 1. delete all the extra render elements CXRs 2. Open each file (6 - 12K images) and then 3. save out a 16-bit TIFF of all the render elements.
BTW, all of this would be avoidable if there was a checkbox on the LUT operator that said "VFB only" or "do not apply to final output". Maybe there's some techincal hurdle that makes this difficult. But I think there are a few of us that would really appreciate this. Sadly I think this is a pro feature that will never ever get any votes or attention.
