I don't have an answer for you, sorry......just some questions if you don't mind. Once a layer package is created I bring it into AE successfully, but cannot find the pop up function. Does AE support pop ups with layers or layer packages. I think not, but may have missed something.
One other issue is when going to 3D mode in AE with these layer packages, the symbols get larger and appear to have some kind of reference scale set. So I actually set a reference scale in AM then reexported to package with same result. It appears layer packages don't honor reference scale settings....any ideas on these issues, thanks.
