Adjust the direction and loop of an animation clip
Refine the generated animations with the Trim tab to improve compatibility with the game logic and character motion.
The generated animations might include a root motion (where the character moves away from the origin) or face inconsistent directions. Use the Trim tab to adjust the direction and position of the animation.
Use the Trim tab when:
- You want the animation to play in place.
- You need all the generated clips to face the same standardized forward direction (positive z-axis in the Unity Editor).
- You want to detect the best loop segment within the animation.
After you have generated an animation with Text to Motion or Video to Motion, follow these steps:
In the Generations panel, select a generated animation.
Select the Trim tab.
(Optional) Enable Root Motion to allow the character to walk away from the origin.
(Optional) Enable Best Loop to find the best loop segment in the animation. The Start and the End markers define the search range.
Review the loop quality color indicator in the timeline. The timeline bar displays the loop quality with the following colors:
- Green: Excellent loop
- Yellow: Good loop
- Red: Poor loop
If you disable Best Loop, the Animation Generator uses the exact Start and End markers you set, without searching for the best match. You can still evaluate the loop quality based on the color indicator and adjust markers manually to improve results.
To create a smooth transition between the start and the end of the loop, select Loop Pose in the Inspector window.
Enter a value in Minimum Duration (in seconds) to define the minimum acceptable loop length.
Select Trim.
For description of all the options in the Trim tab, refer to Trim reference.
The Animation Generator creates a new animation clip with a TRIM label in the Generations panel. This label indicates that the animation is a modified version of a generated clip.
