At some point in my car project, I am going to want to ‘turn on’ the headlights and create a volumetric look as though there are particles in the environment. So as I searched for a third attribute to test, I figured I would test subtle variances in the colour temperature of the light.
I checked ‘use color temperature’ in the Arnold settings for the spotlight and iterated up in increments of 100 degrees kelvin –
What I have learned –
I tested the colour spectrum between slightly yellow light at 5000 through netral ‘daylight’ at 5500 and then through to a bluer light at 5900. I would depend on the manufacturer but I think I will just do what feels right for the scene. Now I have a great look up chart.
