Kelvin scale

 

 

 

The Kelvin scale is a series of temperature idx_73f13f7bunits that can be used to create realistic natural lighting emissions in our scene. As you can see in the following diagram, if we set the Kelvin value for our sun to 5500, it will emit daylight:

But how can we useidx_813bb311 this scale with our sun? This is where the Blackbody node comes to play.

The Blackbody node converts idx_0255f9a2the Kelvin temperature idx_eb6e881evalue to an RGB value.
