Title: VFB Exposure vs Corona Color Correct Exposure and HDRI
Post by: dj_buckley on 2021-03-10, 18:10:43

Just trying to understand the difference between the VFB Exposure and the Exposure setting in the Corona CC Node.

For example, if I have a scene lit only with a HDRI in a Corona CC Node and adjust the VFB to exposure to -2 and leave the CC node at Exposure 0 it looks vastly different to leaving the VFB at 0 and adjust the CC Node to -2

Is this expected?  I was anticipating the end result to be the same if no other variables change?

I'm getting identical rendering in both cases, maybe you're doing something wrong? Can you show what you get?

I'll upload a comparison image using the support links as it's confidential

I've just figured it out

I've got a reflection override, so if I adjust the exposure in the CC node, it doesn't affect the reflections which are artificially pumped up using the RGB Level.

My bad
