[Max] I need help! / Re: ACES in depth ?

Bumping this.
We have discovered that using ACES destroys most of the dynamic range in EXR renders (16-bit half float or 32 float, same result). So when you load the EXR into for example PS and reduce the exposure, you don't recover any data at all. It just goes to a grey/black mush. As soon as I disable ACES and re-save the EXR I get full dynamic range again.
Is this working as intended? If so this is really problematic because being able to recover dynamic range in EXRs is super useful sometimes, for example when basically your whole render is perfect but one area is a bit blown out, you can just load in a second version of the EXR, lower the exposure a bit, and merge that bit back in.
Is there not a way to use ACES while retaining the usual amount of dynamic range?
