How to Control Texture Alpha Transparency in Maya

 

 

The Transparency channel specifies the object's transparency.

Objects can have a uniform transparency throughout the geometry or in limited areas. By assigning a grayscale map to the transparency channel you can set the opaque sections (Black) and the transparent portions (White).

The transparency option is available with Anisotropic, Blinn, Lambert and Phong shaders.

 

Step One

Open a scene with an object. Right-click the object and choose Assign New Material > Lambert.

Step Two

The new Lambert shader panel opens in the Attribute Editor. To change the transparency, move the slider.

Step Three

The color rectangle affects the object's transparency color.

Step Four

Click the checker-box next to the Transparency slider to assign a grayscale map (White = Transparent, Black = Opaque).

Step Five

In the Create Render Node, 2D section, choose Normal and click the Bulge icon.

Step Six

Render your image an note the effect of the transparency map. You can also adjust the Bulge settings. In addition to procedural textures such as Bulge, you can also use grayscale jpg or tif files.

Shadows and Transparency

To render a transparent object with shadows, be sure to use Raytrace shadows. Depth Map shadows don't see the transparency map and the shadow renders as if the object is solid.
