ModifierManager
"Allows you to add a modifer to selected objects (each modifier is a seperate modifier - not an instance of the same modifier which happens if you multiselect objects and apply a modifier in the modifier panel) - and to delete modifiers from selected objects (Any selected objects will have their modifier stacks checked - and any modifier that you specify in there will be deleted.) Replaces RemoveModifier
version 1.50 Added the ability to delete all modifiers on the selected objects."
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.
