AOV group 'Light mix node' compositing in AE

[jeremyshin]

Hello its me again,

I am testing the 'Light Mix Node' AOV preset for a project.

When I composite all my Lights passes in After Effect I have a slight color difference compared to my beauty pass. It looks slightly darker.

I am using the ACES tone mapping option in the Imager as well as render my passes in EXR(Octane) 16 bits.
I tried Screen mode, Linear Dodge mode and almost every kind of project setting possible in After Effects, still can't get the exact same result as my beauty.
My beauty seems correct, same as the live viewer.
It seems that after compositing it loses the ACES response curve and end up a bit more burned out than my beauty.

You can see my setting on the attached screenshots.

What may I do wrong?

Thank you Elsksa!

See attachement picture, is it what you are talking about?

So, if I want to have my AOV passes correct, I need to go through the standard ACES workflow with the openio file, am I right?

Then this means the 'ACES Tone Mapping' in the imager is just a 'fake' ACES and should be used just for straight renders, no compositing? pretty confusing
