PRS Parameters

Provides tools for creating and deleting keys. PRS stands for the three basic transform controllers: Position, Rotation, and Scale.

Reference

Create Key/Delete Key: The six buttons in the PRS Parameters rollout let you create or delete a transform key at the current frame. These buttons become active or inactive depending on the existence of a key type at the current frame.

For example, if you're on a frame containing a Scale key, the Scale button is inactive in the Create column because a key already exists. At the same time, the Position and Rotation buttons are inactive in the Delete column because there are no keys of that type to delete.

Position/Rotation/Scale: Determines the contents of the Key Info rollouts that appear below the PRS Parameters rollout on the Motion Panel.

How To

To create PRS transform key:

1. Select an object.
2. In Motion Panel/Parameters, drag the time slider to the frame where you want to place a key.
3. Click one of the following buttons in the Create Key area of the PRS Parameters rollout:
• Click Position to create a Position key.
• Click Rotation to create a Rotation key.
• Click Scale to create a Scale key.

If a particular Position, Rotation, or Scale controller does not use keys, then that button is not available in the Create Key area. For example, you cannot create Position Keys if a Noise Position controller is being used.
