No, the inputting of metal IOR in Octane Blender isn't the most intuitive. I think it's mostly due to some limitations in Blender's node system (no "tuple" type, etc).

I while ago I got tired of collecting the IOR values and entering them into the inputs etc, so I made a "library" of it: https://chris.hindefjord.se/resources/rgb-ior-metals/ (The values from Chaos group for v-ray are in in "byte"/"integers", while Octane takes the full floats)

Thanks Chris, very appreciated this your contribution!
