Animation Problem When upgrading to Unity3d 4.5

Hi,
Animation was working perfectly in Unity3d 4.0.1 version but when I upgraded to 4.5 it first displayed a warning in console:

MuscleClip 'krishna110@run' conversion warning: 'Root/Hip' is between humanoid transforms and has rotation animation. This might lower retargeting quality.

and the behavior was completely changed. The bone config for the Humanoid is as shown below:



I am not sure whether the problem is related to the naming structure of the bone or something else?

Any suggestion on how to resolve this issue will be helpful

 

Thank for your reply. But can you clarify what exactly it means "Root/Hip is between humanoid transform " and as you have mentioned "a transform between two humanoid transform"

As you can see in the bone configuration that -> Hip is the child of Root and there is no much extra transform. What exactly it is indicating to when it mentions "Between"?

It will be very helpful if it can be clarified.

 

Sorry if I'm hijacking the post but it looks like the OP has been resolved and I just wanted to clarify the warning/error message.

So this warning can be ignored.
I'm happy with the results of my animation. I don't see any difference at all with the animation.
If both object are aligned you will see some minor difference, if you can live with these minor difference you can safely ignore this warning

If you want to resolve this warning you have to remove all the animation on transform that are between two humanoid transform.
Is there a way to resolve the warning in Unity so it doesn't appear again on the same rig/avatar? Something that is more simple within Unity, than going back into the original source animation file, outside of Unity and deleting random translation keys that are placed on bones.

I don't even understand why I'm getting this error actually. I would expect this error if I was animating using FK translations and moving a child bone away from it's parent bone OR scaling a bone which mecanim does not currently support. But I've only animated using rotation keys and IK translations.
By only keying a character using rotation and IK translations this warning message seems to be detecting something that isn't actually happening.

Thanks for any clarification

 

Sorry to revive this topic after such a long time.
I'm trying to get humanoid rig to work with facial animation (generic works fine), but when I apply the animation and set up the rig to humanoid, some bones lose their animation completely (in this example the eyebrows are working, but the jaw does not.). I've turned everything I couls in the mask section. I get that message that the bone is inbetween humanoid transform, but I lose the animation completely on that bone. I could survive some slight errors, but this is weirs.

 

This is documented - have you checked in the documentation about humanoid rig, or - might have been in the blog post about the humanoid rig.

Which bone is it that is between humanoid transforms?

 

It's the bone that moves the Jaw. I animated it using rotation. Is it possible that it ignores rotation only?
