In a bid to improve the boolean workflow in 3Ds max, I created the boolean manager script.
To use, make a selection in 3DS max, two objects or more. The last object you select is always considered to be the object with the boolean modifier on. For example, if you have 5 objects selected, and hit the “sub” button, objects 1-4 will be booleaned into object 5 in your selection.
All boolean objects and cutters are managed and auto-named by the script, the base object will always be named _bool_1_add in the hierarchy which will allow you to edit the source geo independently of the object with the boolean applied.
