I see, that's an interesting scenario that I've never tested (archiving before rendering).
By default, max can't see the full file list for tyCaches so yes, you will have to manually copy all the tyCache files yourself.
However, the bigger issue is that when max archives, I think it converts paths to relative but tyCache currently searches for the absolute path provided by the user. Perhaps that's why it can't see things on your renderfarm. I'll have to test this further...
Martians: can you provide more information about your setup? VRay version, max version, maybe a sample file, etc.
