 In the Timeline, right-click (Windows) or Command-click (Mac OS) on the
Texture tag’s name and from the context menu that appears, choose New Track
> Parameter > Material.
You’ll see a Material sequence appear in the Timeline. You’ll need to add two keys for this animation:
a key at the start that contains the checkerboard material, and a key at the end of the material morph
animation that contains the marble material.
 Ctrl-click on the sequence at frame 0 to create the rst key. The checkerboard
material will be assigned to this key automatically.
 Ctrl-click on the sequence at about frame 45 to create the second key. Again,
the checkerboard material will be assigned to the key automatically, but this
time it needs to be changed to the Marble material (see next step).
 Drag and drop the marble material from the Material manager into the
Material box in the Attribute manager (the Material box for the Material
sequence). This assigns the marble material to the second key.
 Done! Render the animation to see the effect (you won’t see the proper
effect until you render).
