Endomorph is a method for assigning alternate locations to points in the model (i.e. morph targets). By defining an Endomorph in the object, you can set the model for different poses that can be animated or blended with other Endomorphs in a completely non-linear fashion. This is a great tool for facial animation and lip sync.

One major benefit to this system is the ability to make changes to the point/polygon count of your model. Most morphing systems require that the base model has the same number of points and polygons as the target models. This means that once you’ve started building target models you can’t add or subtract geometry from the base model without making the same changes to all the targets. 

With Endomorphs you can make changes to the base geometry and these changes will be copied through the endomorph maps.

Once the Endomorphs are added to an object they can be animated through the Endomorph Mixer panel,

or by modifying channels in the Graph editor.

The Endomorph Mixer is a floating palette of sliders, one slider for each independent Endomorph. You can quickly animate these values by advancing to a frame and adjusting the sliders. This provides a simple and fast method for creating lip sync and other multi-layered morph animations. For more precise control you can use the Graph Editor and directly manipulate the channel for each endomorph. This also allows for the attachment of channel modifiers such as adding noise to a channel or simply locking an endomorph to some other value in the Scene
