MakeUnique
Takes a selected object and makes it unique (ie - if it's an instance of another object - it will no longer be an instance). Originally found as part of Blur's Object utilities - now here it is in script form.
For a max 5 - 4.2 version of this script - please download bspack_r4_r5_v031.zip. Use the original bspack_r42.zip if you want only max 4.2 compatibility.
The only major differences between script packages are slight version compatibility issues - there are no new scripts added between the 3 packages.
