Hi, before FP6 there was an unique folder with all material libs ("matlib" in the root path), and other for the maps ("maps").
We keep the same structure for these libraries, to avoid incompatibilities with existing scenes.
But for the new libraries, each one have its own local folder for materials and libraries ("matlibs" and "maps", within the folder of the library).
This structure is more convenient because all dependent files are stored together. Also it was necessary for Update Manager, to unpack all files of a same library in an unique location.
This change should not affect in any way to the materials ("matlibs"), because each libray has a custom script to load the their materials from the right location.
This is done when a item is imported in the Library Browser.
Regarding the maps, Forest already includes an process to collect recursively all "maps" folders.
These folders are added to Customize->User Paths->External files. In this way, Max can locate and load the textures automatically, and the "relink" process should not be necessary.
The collecting maps process is launched once by Max session, the first time a Forest object is used. It works both in workstations and render nodes.
