Toon BSDF and Shader to RGB not fit for me, and I trying to create flat color shader in cycles. I decided to use this shader, and it works well, until the metallic roughness not "0", then it is reflect like diffuse. I was looking for it on other questions, but there shaders not completely flat. And I want just shadeless material, and this should be reflect like flat. This s blender file, if you want to test shader quickly

Edited: Diffuse shader added to not to illuminate objects around

Edited 2: Partially resolved with adding "Is Glossy ray" output to "Fac", but some part of rays still illumnate objects around. Not final resolve

  • $\begingroup$ Hello :). The Emmision shader with strength=1 will give you exactly that. A flat color not receiving any shadows or lights. $\endgroup$

  • $\begingroup$ @JachymMichal So am I doing this, or what do you mean? This shader does not work in reflection, when roughness chahging $\endgroup$

Flat Color

  • plug RGB node directly, there is no need to use Emission shader

Flat Color in Reflection with Roughness

  • math Light Path of Camera Ray with Glossy Ray** and use as factor in Mix Shader node

Shadow

  • current setup generates shadow, if you dont want that plug Transparent shader into top Shader socket of Mix Shader node.

For your Edit2: Delete your Diffuse Shader that generates indirect light on surrounding objects.

Great article to check How the light path node works
