Since the incorporation of ACES, I was applying the Color Profile Converter in After Effects (ACEScg AMPAS S2014-004) to the EXR with Arnold's Noice to my renders in order to obtain the same result as in Arnold Render View. Which was working fine.
Recently I have found it differs from what I see in Maya. The odd thing is if I try a different image format like PNG it works fine.
I render in a local farm, the versions of Maya and Arnold are the same. I think the issue only occurs when I change the exposure of the HDRI image other than default. It seems that either the EXR format or denoiser has trouble with it.
Has anyone a work around? Is this a bug?
I have included an example. To the left the EXR batch render (overexposed), on the right the render intended that result from Arnold Render View or batch render in PNG.
