The most basic NPR shaders

Basic toon shader (Eevee)

How this works:

1. It takes the grey values from the diffuse BSDF,

2. Shader to RGB Turns the data (casting in programming speak) into RGB colors. Without this we cannot change the colors using a color ramp,

3. The Color Ramp node remaps the grey values to the color you want,

4. Finally outputs it.

Basic shadeless shader (Eevee)

Method 1:

Method 2:

Method 3:

Basic toon shader with texture and alpha (Eevee)

How it works:

1. This is essentially a masking material.

2. The texture going into the factor of the Mix shader node is a grey value. It determines the mixing factor of shader 1 and shader 2. White color shows Shader 2, black color shows Shader 1

3. The difference node (a mix node) compares the original texture to color 2 (the color we want to remove when texture do not have alpha channel, black if it has alpha).

4. The less than node (a math node) refines the edges of the mask using the threshold value.

5. The diffuse BSDF node can be exchanged to Emission shader for shadeless texture or a more elaborate setup.

6. Remember to change Blend Mode to either Alpha Clip, Alpha Blend or Alpha Hatch. Which of these Blend mode you choose will depend on your use case.
