Deleting Unused Keyed Attributes
Maya 2012 Tutorial
How to Remove Keys in Maya
It is common to create animations that include several keyed attributes that remain static and don't change over time. This technique is used to remove any static keys before you render your movie. In this example we will deliberately add several static keys to the animation.
Add a soccer ball to the scene by choosing Create > Polygon Primitives > Soccer Ball.
Select the ball and open the Channel Box.
Click frame one of the Timeline and press the s key.
Click frame 24 of the Timeline, enter 8 for Translate X in the Channel Box, the press Enter + Esc + s key.
In the Channel Box,and notice how keys have been added for translate, rotate, scale and visibility. The only keys we need are the translate keys.
Choose Edit > Delete All By Type > Static Channels and the excess keys are deleted.
Removing a Key from a Specific Attribute
If you need to remove a key from a specific attribute (i.e., color in a Blinn Shader), right click the word Color and choose Break Connection.
