PRS Parameters Rollout

The PRS Parameters rollout provides tools for creating and deleting keys. PRS stands for the three basic transform controllers: Position, Rotation, and Scale.

• Select an object > Motion panel > Parameters > PRS Parameters rollout

Procedures

To create a PRS transform key:

1. Select an object in the viewports.
2. Drag the time slider to the frame where you want to place a key.
3. On the Motion panel, choose Parameters PRS Parameters rollout.
4. Click one of the following buttons under Create Key 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 doesn't use keys, then that button is not available under Create Key. For example, you can’t create Position keys if you're using a Noise Position controller.

Interface

Create Key and Delete Key groups

Creates or deletes a move, rotate, or scale 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.
