Hi rcates,
From images, I can’t tell. If I can get the scene file, I will explore it.
What you can do, perhaps create a Multi-pass with a pass for each light.
Check the options of the editor.
Anything else would be a long guessing session, which I always find very unprofessional, as I believe it will take too much of the time of the one with the problem.
(Edit: With not professional, I mean that dumping many questions and guesses into the forum would be unprofessional from my side. I find platforms with that kind of stuff in it super hard to read, challenging to follow, and wasting everyone’s time. Instead, I offer to look at the file, and when I get a reproducible solution, I post the answer and perhaps some alternatives. Besides, I started a few years ago to make 60-second clips, “running” through a setup, to visualize the setup. (Nearly 1300 clips by now.) It seems to work. Otherwise, the communication might be extended. Sorry, it was never meant to characterize nor evaluate the question or the one who asks itself. Not at all! Really sorry. Well, now I took a lot of time. I hope it is OK./edit)
Do you need an upload link? (If you have Dropbox, Amazon, Adobe, Apple, Google, or Wetransfer, I will use it, other cloud services will be ignored for security reasons.
Cheers
