References Falling Out Of Groups

[vonfokker]

Has anyone had a problem in maya 7.0.1 with references falling out of their groups.

Basically I have referenced in some characters and then have grouped them within my scene. They seem to group fine, but when I save the file and come back to it later, they are no longer in the group.

I am going to try constraining them instead, but I am curious as to why this is happening as there are no errors in the script editor. I have done this same procedure before, but have noticed that it happens every once in a while.

Any ideas?

Thanks,

One thing to try is cleaning the reference. Make sure the reference is loaded, open the Reference Editor, RMB on the reference, and then File > Clean Up Reference.

Did you group the references manually or using the Group option when creating the reference? Also did you create the reference using namespaces or renaming prefixes? I'd recommend namespaces as renaming prefixes are known to have a lot of problems.

In general referencing has trouble when there is ambiguity over node names, this can happen if your referenced scene has a lot of instances or duplicately named objects, or if you have complex parenting relationships between main scene and referenced nodes. The use of renaming prefixes can also make things tougher for Maya to noodle out.

Thanks for the response.

I grouped the objects manually within the scene and am using unique namespaces for each object.

I will take you advice and double check the naming conventions and try the clean up reference command.
