Hi Im rendering passes from Cinema 4D and I need 32-bit workflow so my multipass workflow to be correct. I added an optical flare and I also added a "Color Profile Converter" effect so that way the flare work correct in linear workspace, but I still have an issue with overbright parts - I get negative values there, resulting in yellow-red to black pixels. How to avoid that issue? I tried with HDR comp[ander but no luck, it just removes the lens effect.

You must have extremely bright overbrights.

You can use a Levels effect on the flare to limit its overbrights. Set both the Input White and Output White to the same value greater than or equal to 1 and change Clip to Output White to On.
