Blackbody Node in Blender

Blackbody Node in Blender.
A blackbody is an idealized physical object that absorbs all electromagnetic radiation that falls onto it and emits radiation at all wavelengths depending on its temperature. It's used as a theoretical model for understanding the behavior of real objects in thermodynamics and quantum mechanics.
In this short video, I explain the use of the Blackbody node in Blender, which allows artists to get accurate color temperatures.
