Bloom results in black screen - Unity 2020.1

Unity Engine

We did a quick test branch with Unity 2020.1. The bloom post-fx outputs a black screen when certain objects are in view. Stop NaNs is activated. The same scene-setting in 2019.4.2 is working fine.

Unity 2020.1
HDRP 8.2.0

Any news on this issue?

Hello, a few questions:

  • What is the precision for “Rendering>Color Buffer Format” and “Post-Processing > Grading LUT Format” (and Buffer Format) in your HDRP asset? And did you try to alter these settings?
  • Also, you mention the problem appears when “certain objects are in view”. Can you be more specific? If you hide said objects, is the problem fixed? did you then try to isolate the material property/shader that badly affects the bloom?
  • Is it actually a Bloom issue, or an exposure problem related to a pixel being extremely bright potentially? Does the problem disappear with a Fixed Exposure?

Hi, you have NaN checker in the Render Pipeline windows, → rendering section, it will allow you to identify which object is hill formated. Bloom in this kind of cases is very rarely the guilty.
