What's New in Character Animation in Maya LT 2017 Update 3

Filter for controller nodes

A new Show Controllers Object option has been added to the Display menu Show options to let you filter your scene for Controller objects, regardless of type (NURBS, locator, or shape).

Deformer Improvements

Bake Deformers
The new Bake Deformer Tool calculates smooth bind weights that approximate deformations from arbitrary deformers.
Bake Deformer lets you export complex rigs to applications that have limited deformer support, as well as being a quick trick for determining default character bind weights.
You can currently only open this tool through the Maya Command Line using the BakeDeformerTool command.
Updated deformerWeights commands

The examples for the deformerWeights MEL commands in the Technical Documentation have been updated for clarity and expanded to provide more detail. For example, you can now copy and paste the command examples into the Script Editor.
