@VIZSET as Tom explained, the ACEST OT operator in the Corona tone mapping stack is something like an advanced version of a LUT, which just makes your image look nice.
Could you please explain what exactly is your problem? You are saving an image from the Corona VFB, loading it into Davinci Resolve, and you are getting different colors?
Hello!
Yes, problem with different colors when I save an exr from VFB and import it to DaVinci (when ACES OT on or off - it's doesn't matter). Importing the same exr to photoshop goes correctly.
