Custom Attributes node referencing
I've encounter an issue with node referencing within custom attribute, when merging a scene in another one.
From the files I've attached (max 2016), the two scene are identical except that on sceneCA.max, sphere001 has an CA that reference sphere002.
Now when I'm merging sphere001 from sceneCA.max into scene.max and replacing the original sphere001 (without merging sphere002), the referencing on the CA doesn't work anymore.
Does anyone would have any idea to avoid the reference breaking in this situation ?
