To assign a shader to a surface

1. Pick the surface(s) in a modeling window.
2. Pick the shader in the Multi-lister.

   See Assign Shader in Render > Multi-lister .

3. Select Shading > Assign Shader in the Multi-lister.

To layer shaders onto a surface

1. Pick the surface(s) in the modeling window.
2. Pick the shader in the Multi-lister that you want to layer another shader on top of.

   See Assign Shader in Render > Multi-lister .

3. Select Shading > Assign Shader in the Multi-lister.
4. Pick the shader in the Multi-lister that you want to be layered on top of the first shader.

   See Layer Shaders in Render > Multi-lister .

5. Select Shading > Layer Shaders in the Multi-lister.

What is required for shaders to work

Shaders determine what surfaces look like (for example, color, reflectivity, roughness). Once you create a shader, you can assign it to one or more surfaces. You can also layer more than one shader onto a single surface.

In order for a surface to have the properties of a shader, you must assign the shader to the surface. You can assign a single shader to several different surfaces. You can also layer several shaders onto a single surface. By default, all surfaces have the DefaultShader assigned to them.
