Cannot freeze transformations in Maya


I'm trying to freeze transforms in Maya, for an object that has animated children, but is not animated itself. (Explanation will follow in detail)

First of all, is this possible? Because it should be, so my intuition tells.

My hierarchy is like this :

- ChildObject

ChildObject has animations, however ParentObject hasn't any. I removed them manually from the Graph Editor. I also deleted all history on ParentObject, but still, when I select ParentObject from the Outliner, and call DeleteAllHistory; FreezeTransformations; I get the error message : // Error : line 0: Freeze Transform was not applied because ChildObject.translateY has incoming connection

It doesn't even make sense because I select Parent, and not the Child. Does it automatically selects the child. If so, how can I prevent this behaviour?

Thanks for any help !


One possible solution is to select the Parent and group it, so add a grandparent. But I don't want this to go on, until I have

- GrandGrandGrandParent
 - GrandGrandParent
  - etc

so I want to know what I'm doing wrong, so I can fix it in later, probably more complicated situations. Thanks again !

No and yes, freezing moves space. Thus the numeric values of any child spaces are moved around loosing meaning. To protect users from themselves its not allowed, and it does not make sense. Spaces under children are not affected as long as the child can be resolved, because the child space didnt change. (children are defined in their parents spaces)

You can re shift/scale the children, unless the space was rotated. Or you could bake down the transformation to world space and back. This is a bit error prone tough and you would need to write the script yourself.

PS. I keep telling people freeze isnt a tool you want to use to organize channels for easy editing. You should avoid freezing at all cost, once your data is comitted freezing is rarely possible. So once you go and freeze or animate your mind better be made.
