Shaders can be used to set up how a material reacts with visible lights. In the material panel, we can choose two types of shaders, which are diffuse and specular shaders.


A diffuse shader determines how much light is reflected by the surface. Let's make things clear here—it doesn't mean that the object will generate illumination. If we set up a high reflection value for the diffuse shader, it will mean that the object will be brighter.

We have five different kinds of shaders in the Blender materials panel:


All these shaders share common parameters, like the Ref. This option sets how much light is reflected. So, if we set up a high ...
