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

Switches double float attributes on a 2D texture, like Repeat UV or Translate Frame of a 2D texture placement.

To use the Double Switch utility

1. Create a material and assign it to the objects.
2. Map a 2D texture to one of the material’s attributes, such as Color. Adjust the texture’s attributes if necessary.
3. A place2dTexture node is created when you map a 2D texture. Double-click the texture’s place2dTexture swatch in Hypershade to open its Attribute Editor.
4. Place the cursor over the Repeat UV attribute, and right-click Create New Texture from the pop-up menu.
5. Select the Double Switch utility from Maya > Utilities in the Create Render Node window. Notice that the spheres seem to have lost their textures.

   This is when you can apply a Default setting in the doubleShadingSwitch Attributes Editor. You can either map a new texture, or change the values for U and V. In the following the Default value is changed to 1.5 for both U and V.

   

6. Open the Outliner ( Window > Outliner) and use the middle mouse button to select the spheres for which you want to adjust the UV texture placement and drag them to the inShape column of the Switch Attributes.

   

   Notice only the spheres you move into the inShape column lose their textures. These are the spheres you want to change.

   

7. Click to highlight the inShape column then click the Map Item button.

   

8. Select the 2d Placement utility from Maya > Utilities in the Create Render Node window. The Connection Editor appears. Click the Repeat UV Output node (in the left column), then the Input[0] In Double Input nodes (in the right column).

   

   Only the spheres you mapped in the Double Shading Switch’s Attribute Editor update. Click the place2dTexture swatch in Hypershade to open its Attribute Editor and adjust the Repeat UV values if necessary.
