Hi Mark and Marcus. The MAsset code I wrote managed uuids on duplicate callbacks. You could re-use / re-factor that. Worked throughout GoldenEye without any issues.
Also the cool thing about that uuid was I could add several nodes to the same uuid and treat them as one MAsset, In effect Maya's containers, without the bugs at the time. If for any reason the metaData connections are lost then you have the uuids to match them back up. I'd prefer an alternative though!
