Max Script Package

I have installed the 3ds max script package, but I have no idea how to tell Atom that I wish to use it.

Please post a link to the package’s page on this web site. I’m not familiar with that one and searching for “3ds max script” doesn’t turn up anything.

I am not sure how to do that.

What did you type in to search for the package in Atom? Type the same thing into the search bar in the Packages tab of this site, find the one you’re using, and paste the link here.
