This workflow, named "360-Degree Rotation", generates smooth object/character rotation animations for e-commerce displays, game character previews, etc. Key features:

  • Converts a single image into a 360° rotation sequence

  • Powered by Wan2.1 video generation model

  • Customizable rotation angles and frame rates

  • Enhanced with 360度旋转lora_flux LoRA for motion optimization

4. Workflow Structure

  1. Input & Preprocessing

    • Input: Single image (e.g., 07-空.jpg)

    • Processing:

      • Resize to 480x480 (ImageResizeKJ)

      • Feature extraction via WanVideoImageClipEncode

  2. Rotation Generation

    • Load Wan2.1 model + rotation LoRA

    • Generate 33-frame sequence (prompt: 电表360度旋转)

  3. Output

    • MP4 video (WanVideo2_1_*.mp4, H.264, CRF=19)

5. Inputs & Outputs

  • Input Parameters:

    • Required: Single image (PNG/JPG)

    • Optional: Resolution (default:480x480), frame count (default:33), negative prompts

  • Output: 360° rotation video (saved to ComfyUI/output)

6. Notes

  1. Dependencies:

    • Manual download required for Wan2.1 and VAE models.

    • Rotation LoRA must be placed in models/loras.

  2. Hardware:

    • Recommended: ≥10GB VRAM (NVIDIA GPU).

    • Increase WanVideoSampler steps (default:20) for higher frame counts.

  3. Optimization:

    • Adjust WanVideoTeaCache (default:0.16) for smoother rotation.

    • Use plain backgrounds for best results.
