Skinning Editor PSB Rigging Not Applying in 3D URP Template Project

I encountered an issue where the Sprite in my PSB file does not move along with the Bone after applying it through the Skinning Editor and placing the PSB into the Scene.

[Video of the Issue]

Details of the Situation:

  • Unity Version: Unity 6, 6000.0.32f1
  • Started the project with the 3D URP template, then added the 2D package.
  • Imported a PSB file into the project, applied Bones and Weights using the Skinning Editor, and verified everything was properly set up. However, after clicking Apply and dragging the PSB into the Scene, the Sprite did not move with the Bone.
  • Confirmed that the Sprite Skin component is attached to each Sprite. Even with the component, it did not work as expected.

Steps I Tried to Solve the Issue:

  1. Reimported the resource: No effect.
  2. Exported the project as a package from a 2D template project and imported it into the 3D URP project: Did not work. But it worked perfectly in the 2D template project, so this doesn’t seem to be a version issue.
  3. Used prefab examples from another developer: Partial success. When using the prefab example provided in the tutorial, it worked as expected: Bones and Sprites were linked and moved correctly, and animations worked fine. However, when I added the original PSB file from the tutorial to the Scene, the same issue persisted.
  4. Enabled Auto Rebind in the Sprite Skin component and reconnected the Root Bone, Reset Bind Pose: No effect. When dragging the PSB directly into the Scene, the Root Bone was set to the PSB object itself. Changing it to the correct Root Bone did not resolve the issue.
  5. Unpack Completely: The working prefab had a solid cube icon, while my PSB object had a hollow cube icon. I tried Unpacking Completely to match the hierarchy, but this did not make any difference.

If anyone knows how to resolve this issue, I would greatly appreciate your help! Thank you!

Hi,

I believe Sprite-Unlit-Default is the Material being used above.

We are working on a fix for this issue. Please use the following link to track the case:

A temporary workaround would be to disable GPU-Skinning in Player settings.
Will post an update as soon as the fix is available. Sorry for the inconvenience caused.
