Error in animation rigging

honestly, this is completely asinine, but if you're getting errors like this:

Could not resolve 'Armature/ThingToLookAt' because it is not a child Transform in the Animator hierarchy. nvalidOperationException: The TransformStreamHandle cannot be resolved. UnityEngine.Animations.TransformStreamHandle.CheckIsValidAndResolve (UnityEngine.Animations.AnimationStream& stream) (at :0) UnityEngine.Animations.TransformStreamHandle.SetLocalTRS (UnityEngine.Animations.AnimationStream stream, UnityEngine.Vector3 position, UnityEngine.Quaternion rotation, UnityEngine.Vector3 scale, System.Boolean useMask) (at :0)

think back to the latest thing you nested under that root object. It drove me nuts and this came from seemingly out of no where, but by nesting a prefab inside anther prefab, Unity threw this error at me. It was located at something like: parent > armature > root > spine > spine1 > spine2 > spine3 > shoudler > arm > forearm > hand > prefab > nested prefab. This drove unity's job system fucking whacko, and did not solve itself until I removed the parent object of the nested prefab (there was a child and a parent, and I only used the parent for the offset).

Apparently the animation rigging component only goes so many children deep before it bugs out.

I don't expect this to help anybody out, but it was legit the issue for me.

Animation Rigging allows the user to create and organize different sets of constraints based on the C# Animation Jobs API to address different requirements related to animation rigging. This includes deform rigs (procedural secondary animation) for such things as character armor, accessories and much more. World interaction rigs for interactive adjustments, targeting, animation compression correction, and so on. CFAHome Login
