    Hello,

    I am getting the following exception from physics baking system after upgrading to latest (1.0.0-pre.15) (Entities, Physics, Graphics)

    As such the stack trace has zero of my source code.

    InvalidOperationException: Baking error: Attempt to add duplicate component Unity.Transforms.PropagateLocalToWorld for Baker PhysicsBodyAuthoringBaker with authoring component PhysicsBodyAuthoring. Previous component added by Baker PhysicsBodyAuthoringBaker

    It seems as if you are passing a duplicate component (Unity.Transforms.PropagateLocalToWorld) with the baking PhysicsBodyAuthoring. Let me know if the issue persists maybe send a zipped project

    Hello

    As you can see from the stack trace there is zero of my code.

    Without any changes my setup worked on previous version (1.0.0-pre.12).

    Did you clean the temp files such as Temp, Library, Logs? Could you maybe send the project as a Zip file?

    switch to 2022.2.0f1 editor version and it will not break. Just did it and works well, no console errors.

    I have the same error, using Unity 2022.2.1f1.
    I use multiple dynamic bodies in a hierarchy, connect with joints. I took the bakers provided in the Physics samples.

    I cleaned temp, logs... and fully re-imported the project.

    InvalidOperationException: Baking error: Attempt to add duplicate component Unity.Transforms.PropagateLocalToWorld for Baker PhysicsBodyAuthoringBaker with authoring component PhysicsBodyAuthoring. Previous component added by Baker PhysicsBodyAuthoringBaker
    Unity.Entities.IBaker.AddDebugTrackingForComponent (Unity.Entities.Entity entity, Unity.Entities.TypeIndex typeIndex) (at Library/PackageCache/com.unity.entities@1.0.0-pre.15/Unity.Entities.Hybrid/Baking/Baker.cs:1282)

    EDIT: after some testing I found out the error also happens when you have no nested dynamic bodies (simply bodies connected with joints). It gives a warning that it will be un-parented at runtime but that doesn't indicate the baking shouldn't work... (I have multiple bodies under an empty parent as prefab root)

    Mind that there was still one error but not related to the physics baking system.

    @JosepMariaPujol I did a bug report.

    Also tested a bit more, happens even with single bodies and no joints! Seems to be a general bug when Interpolation or Extrapolation is turned on!

    Also the Transforms are incorrectly updated when using the PropagateLocalToWorld, WorldTransform for example is always 0.

    I remember reading this thread and I just downloaded the new sample just because I was curious https://github.com/Unity-Technologies/ECS-Network-Racing-Sample

    And got the same error from it when I tried to enter game (after car selection)

    The error has been fixed and backported to dots-1.0 physics package. Once we release the minor update version it will include a fix for this issue. Thank you for reporting ❤️
