Added Duplicate, Copy, Paste, and Build Mask to Layer context menu.

Build Mask:

• Generic: Instantly creates a mask that includes all the transforms used by the target layer
• From Animator: Same as Generic, but filters the Transforms based on valid Paths from the selected Animator Root

Build Cumulative Mask:

• From Masks: Merges all the masks that the lower layers use into a new mask
• From Layers: Generates a mask for each layer internally as if using Build Mask then merges those into a new mask without putting them into the lower layers

Added shortcuts for Copy Ctrl + C, Paste Ctrl + V, Duplicate Ctrl + D, and Rename F2.

Layers can be copied from one controller and pasted across to a different controller.

Layer Index is displayed in the layers list.

This can be toggled in Setting Up Controller Editor

Scrollbar will scroll down to newly created layer upon new layer creation instead of snapping to the top.

Scrollbar will no longer reset after editing a layer

Added a dropdown to the toolbar to choose from Template Controllers to instantly merge into the controller.

These are previously created controllers that you can instantly add to your current controller without having to go through the trouble of merging or using any other tools/features.

When used, it will add all the layers and parameters to the active controller. It will automatically handle parameter renaming so that it’s unique. Hold Shift when adding template if the parameters shouldn’t be renamed.

It will automatically generate new copies of any referenced animation clips that are named starting with T_ or if the clip animated an animator parameter that had its parameter automatically renamed upon merging. All other clips will retain their original references.

To create your own templates, see Creating Template Controllers.
