Finally, after some test, jobs and many hour spent on it, I found a reproducible issue with Bloom and Glare that turn off it self that drive me crazy on past year...I'm very happy!! 🎉🎉🎉. I'm a problem solving and bug hunter lover...😅
Here is my Corona Release (see attached about info panel below) and I'm using the Cinema4D 2024.4.0 (Educational License) (Build 2024_4_14d2cb99a70f_1236864028)
OSX.
Seems the problem is related if you
selecting and
deselecting Camera or TAG. Based on some action you can see on the video below, the Bloom and Glare turn off it self during the final render even if it is on into the TAG.
Based on deselection of the camera object the Bloom and glare effect change its behavior by Turing off.
I hope this help.
This issue is not based on this specific scene, it works with all scenes as well.
Look directly on you tube for best watching...video:
