I think you slightly misunderstood my intent. Im saying that to match the coronaPhysical metal in with a physical material i have to set the physical material IOR to 2.5-3.
Coronas metal mode locks the IOR of course, which is physically incorrect anyway because metal ior has a fairly broad range range and absolutely cannot be defined by a single arbitrary number. I would hope this is something that gets changed in future so we can get physically correct metals.
Its the Nvidia GPU denoiser in IR. It just seems to handle the physical materials faster for whatever reason.
#1. Corona colour correct is not linear, if you want to get the same result as with invert in Max's bitmap or output nodes, then you can use curve adjustments in CCC.
#2. If you want metal, then switch Corona physical to metal node. 2-3 IOR is not metal.
#3. what denoising you are using and what image filtering. If that's Corona HQ denoiser, then filtering also should be set to HQ, otherwise it will severely underperform. I didn't notice dependency on material type, but maybe that's because i almost exclusively use Corona physical.
I think you might be confusing map channels with material IDs. They are not the same! I think you're not seeing anything in the viewport because your bottle has no map 2 channel. Simply add another UVW map modifier and set its channel to 2, then you start seeing something and adjust things as you need.
