If you select a surface or 3D geometry in the scene before adding a Shader node, a shader inclusion link is automatically applied; otherwise, the shader is applied to all objects. You can also apply inclusion and exclusion links manually. You may want a shader to only affect an individual or specific group of objects, or prevent a shader from affecting an individual or specific group of objects.
To apply selective shading:
- Add a shader to the scene.
All objects are affected.
- Select Light Link from the Tools box.
- To affect only a selected object, click the Shader node, and drag it to an object you want affected.
The selected object is connected to the shader by a blue dotted line with an arrow, and only the selected objects are affected.

- To exclude an object, hold the Alt key while clicking and dragging from the shader to the object you do not want affected.
Excluded surfaces are connected to the shader by a red dotted line with an “X”, and they are not affected by the shader.
