Use the Single Switch utility

For a description of the Single Switch utility, see Single Switch.

Switches single float attributes, like a Bump Value or Bump Depth.

To use the Single Switch utility

1. Create a material and assign it to all the objects in the scene.
2. Map a texture to the material’s Bump Mapping attribute. Adjust the texture’s attributes and 3D placement if necessary.
   
   Tip

   If Alpha Is Luminance is on in the Color Balance section of the texture’s Attribute Editor, the rendered result is much smoother. Alpha Is Luminance is on by default.

3. In the Bump 3d’s Attribute Editor, place the cursor over the Bump Depth attribute, then right-click Create New Texture from the pop-up menu.
   
4. Select the Single Switch utility from Maya > Utilities in the Create Render Node window.

   The Single Switch’s Attribute Editor appears.

5. Open the Outliner (Window > Outliner) and middle-select one of the objects for which you want object-specific bump mapping. Drag it to the In Shape column of the Switch Attributes.
6. Click the name displayed in the In Shape column then click the Map Item button (or right-click over the In Single column and select Map from the pop-up menu).
   

   The Create Render Node window appears.

7. Select another texture. The Switch AttributesinSingle column now displays the new texture. Adjust the texture’s attributes to get the look you want. Notice in Render View that only one of the object’s bump map changes as you adjust the attributes.
   
8. Now change the Default attribute in the SingleShading Switch’s Attribute Editor. The bump maps on the other objects in the scene adjust according to the value you enter.
