Previously, we used Blend Shapes to create face expressions. Blend Shapes are also an excellent tool for special effects. In this recipe, we will morph one object into another.
To follow this recipe, we need to prepare an object with Blend Shapes. We've created a really simple example in Blender—a subdivided cube with one shape key that looks like a sphere. See the following screenshot for reference:

You can also go to the Chapter 07 Special effects\Recipe 05 Using blendshapes to morph an object into another one directory. Open the Example.unity scene there. You will see a number of cubes there. If you hit the space bar in play mode, the cubes will morph into spheres. You can find the Cuboid.fbx asset with the required Blend Shapes in the Model directory.
