[Trouble Shooting] Where is “Shader to RGB” Node in Blender?

This is a problem I am stuck on, but it is easy to solve.

Problem

I was finding the shade node “Shader to RGB” that converts the output color of a shade into RGB. However I couldn’t find it in Blender 8.3.

Solution

“Shader to RGB” node is prepared for “EEVEE” renderer only. So we need to change the Render Engine into “EEVEE” and we can find “Shader to RGB” in Add > Converter.
