Question [1.0.0-exp.8] is there a way to specify child entities that should not be synchronized?

    For example, I have some text above the player (as a child of the player prefab) that I need to rotate to face the camera. There is no camera for the server, so prediction will always be wrong, nor does it make sense to synchronize presentation-only stuff. Is there a way to turn sync off for specific parts of a prefab? Or is there a better way to do what I'm trying to do?

    Oh yeah, you can customise that behaviour for each individual prefab, by assigning the DontSerializeVariant to the Rotation on the child game you want to exclude.

    However, note that in 1.0-exp.8, by default, we don't serialise components for child entities, so the rotation and translation etc etc are not synchronised.

    To change the behaviour for the prefab, add a GhostAuthoringInspectionComponent to the GameObject you want to customise.
    The replicated components will show in the inspector and you can select for each of them a different variant to use.

    Any idea what's going on here? It seems the GhostUpdateSystem keeps updating this ghost child entity's rotation to 0, which conflicts with my AimAtMainCameraSystem.

    I also couldn't find a way to turn this off in the GhostAuthoringInspectionComponent.

    I need to see how you configured the ghost for give some more information

    I have noticed that if you add a GhostAuthoringInpectionComponent to a child of a ghost, the Translation and Rotation are set to their default serializers instead of DontSerializeVariant. This looks like a bug.

    in 1.0-exp.8 they should be set to DontSerializeVariant. Pretty sure in 1.0-exp.13 (latest release) work that way. We ported a couple of fixes for the UI, variant in particular.

    I'm using 1.0-exp.13 and the result is the same

    I'm using it right now and I have the correct DontSerialize variant.
    So.. I suppose I'm not trying to do the same thing. I will start a project from scratch, without anything into it, instead of using NetcodeSamples or whatever else.

    I've just found a bug in `DefaultVariantSystemBase` and `DefaultVariantSystemBase.Rule` where `DontSerializeVariant`s are not hashed using the new constant hash. Not sure if related to this, but will try to get that fix backported ASAP.
