There's currently no way to white balance Arnold AOVs. Users can fudge it by changing color temperature of lights, but this is no good for accurate lighting studies of architecture, for example.
The Physical camera supports exposure control, but AOVs do not.
Arnold has both a Camera Filter Map functionality and a Blackbody map, which would solve the problem. But the Camera Filter has not been implemented in MaxToA.
I can easily white balance AOVs in Maya, but not in 3ds Max.
Please add a Camera Filter Modifier that accepts texture map nodes such as Blackbody.
Thank you.
