According to OP:
Since now we have a tools section I'll post this tool here too This is a tool for adding UV animations to GLB models used in Ikemen GO. Usage:

1. Open a GLB model. Its nodes will be loaded automatically.
2. Find the node where you want to apply the animation.
3. Set the animation speed and direction.
4. Choose an output directory (optional). By default, the file will be saved in the same directory as the original model.
5. Click "Add to Queue" to add your changes to the animation queue on the right.
6. Click "Apply Animations".

Notes: These animations are generally meant to be applied at the final stage of stage creation.If you open the GLB file in Blender, you won’t be able to see the animations.
