Short description of error
Some shaders not yet available in EEVEE, such as the Toon shader, are included in the list of shaders in the materials tab of the properties window even when EEVEE is selected as the render engine. When such shaders are selected, adjusting most of their parameters has no effect on the viewport/render. Currently, the only way to know which shaders are supported is either by trial and error or by using the node editor.
Exact steps for others to reproduce the error
- With a fresh blender scene, check that EEVEE is the selected render engine, and go to materials tab in the properties window
- You should already have a material if it's the default cube scene. In the surface panel, click on the shader selector (set to principled BSDF by default)
- The menu that shows up includes Toon shader among other unsupported ones.
