I’ve just been playing with the differences between different settings and created a few clips for reference so I can easily tweak the look I’m after so I thought I’d share for others to use.
I have noticed that what renders in the viewport/PV is quite a bit different than what comes out in the exr… like more light information in present. I was sure the PV was 32bit? Anyone else had this?
What do you mean, different? Are you sure you are loading/interpreting the exr correctly?
I think it is that i’m interpreting incorrectly as it is WAY brighter (like attached)
I’m bring it into AE with 32bit (float), linear colour management and Color Workspace set to none for the project.
I think preserve RGB should be ticked as well.
can’t believe it, I think my brain has taken the weekend off. 
Thanks again
