How to Copy Keyframes in 3ds Max?

To copy keyframes in 3ds Max, you can typically use the Edit menu after selecting the desired keyframes and the associated controller in the animation editor, such as the Track View.

Here is a method based on the provided reference:

Method for Copying Keyframes (Example: Camera Position)

This process involves selecting the specific keyframes and the parameter (or controller) they belong to within 3ds Max's animation interface, often done in the Track View editor.

Here's a breakdown of the steps:

1. Access Keyframes: Navigate to where your keyframes are displayed and editable. This is commonly done in the Track View or the Dope Sheet editor.
2. Select Keyframes: Identify and select the specific keyframes you wish to copy. As described in the reference, you might "Go to the last keyframes and select them." (or any keyframes you need).
3. Highlight Controller/Entry: In the hierarchy view (usually on the left side of the Track View/Dope Sheet), find the object and the specific parameter (like Position, Rotation, Scale, or a custom property) containing the keyframes you selected. "Now, click on the Camera01 Transform Position entry to highlight it," or click on the equivalent entry for your object and desired parameter. Highlighting this entry tells 3ds Max which controller's data (including the selected keyframes) you intend to copy.
4. Copy Using Edit Menu: With the keyframes selected and the corresponding parameter entry highlighted, go to the main menu bar at the top of 3ds Max. "then click on Edit Copy". This action copies the selected keyframe data for the highlighted controller to the clipboard.

You can then paste these copied keyframes elsewhere on the timeline or onto a different object's compatible parameter.
