Wan2.1 Sprites Generator Tutorial

This will enable you create consistent character animations with smooth transitions. While it can be used for various animation types, it’s designed primarily for sprite animations.

You can easily tweak it to use it for looping regular videos. see note and example.

Key Concept: Generate Your Character in One Image with Multiple Poses

The core idea is to create a single character sheet image containing multiple poses of your character. This sprite sheet can then be used as input for ControlNet to guide the generation of animation frames, ensuring character consistency and smooth motion transitions.

---

Why This Works

• Keeping all poses in one image helps the model better understand your character’s proportions, colors, and details.

• This unified reference reduces character drift or inconsistency between animation frames.

---

Simple Example: Building Your Character Sheet

1. Design your character poses using tools like PoseMy.Art to generate depth pictures.

2. Arrange these poses side-by-side in one image — for example, a row with idle, walking, and running poses.

3. Save the individual pictures in an empty folder.

4. Use the provided combine.py script to merge these images into a single sprite sheet.
   It’s recommended to choose a dimension close to your Wan2.1 video output resolution for best results.

Feeding the Sheet into ControlNet

• Use your character sheet as the conditioning image input for ControlNet.

• Set your prompts to generate animation frames based on this sheet, ensuring each frame stays consistent with your character’s appearance.

Looping and Finalizing Animation

• After generating your animation video with Wan2.1, find a loop by adjusting the start and end frames to create a seamless cycle.

• If a perfect loop isn’t possible, try making a ping-pong loop or change the random seed to generate another video.

• Finally, save your result for use in your game or animation project.
