Problem with DR rendering an exterior with Forest Pack objects and "transfer assets"

I’ve got an exterior scene with some Forest Pack objects for grass and shrubbery. It renders fine on my workstation, but if I use distributed rendering with “transfer assets” turned on I get errors and some forest pack objects don’t render with correct materials. Please see the screenshot attached below. What could be the problem?

Please disregard. I found the problem. I hadn’t added the External User Paths for Forest Pack in 3ds Max.
