Nested Layer Manager 3 for 3ds Max | Tim Hawker
Nested Layer Manager 3 provides the ability to nest layers in 3ds Max. This script is small, fast and allows layers to be nested in an unlimited number of folders. It has complete 2 way communication with the default layer manager; If anything is altered in either, both layer managers are updated. This allows people without this script installed to still see the normal layer organisation present in the file.
