3dsmax from 2010 to 2023
This tool is free to use.
Have you ever tried to use selection sets in 3dsmax ?
This is a pretty usefull tool, but it’s also very limited since if you merge the file they don’t persist.
NodeLIST is a Helper which does pretty much the same thing as Selection Sets but is easier to manage, with more options, and you can merge it with your other objects.
The Selection Sets are saved in the helper itself.
