carpaint bug

Just look like carpaint shader is broken. It is emissive even in low light condition.

Yes, using pure 100% white Specular channels can do that.
For reference check Carpaint's Preset: "White" to get to see it physically-based.

+ protip: I also strongly advise use of LookDev accessories (colorchecker, gray & mirror ball) for lighting or CC/TM reference and later calibration with Material tests/study scenes. You know, like real pro... ;)

All materials should be energy conserving.. I consider this a bug.
