Maxscript Installation Instructions
Here’s a quick tutorial on how to install scripts. For now, I’m not using an installer, so each script must be run before it is ready to be used. In three easy steps:
First, install the script. On the menu, go to Maxscript -> Run Script... and navigate to where you saved the script. IT LOOKS LIKE NOTHING HAPPENED! That's normal, all you are really doing is installing the script so Max can run it later, when you press a toolbar button, hotkey, menu item, etc.
Now that the script is installed, it needs to be put somewhere in the user interface where you can run it. Go to Customize -> Customize User Interface to bring up the dialog where you can place the script.
In the dialog, choose where the new script command should go. In this case, we are going to put it on a toolbar. A similar procedure can be used to put it on a menu or quad menu or keyboard shortcut. Choose the "EM Tools" from the category - this is where all of my scripts will be found. You can just drag the script you want to an existing toolbar. And that's it! Click the button and it should run right away.
If you don't want to put the button on an existing toolbar, you can create a new toolbar instead. Press the "New" button, type a name in the dialog and press "OK". It will create a little floating dialog bar. You can leave it floating or dock it to the top, right, bottom or left side of the interface. You can then drag icons onto this toolbar.
UPDATING: Updating a script is even easier. You only have to run the script, as in step 1 above. Any toolbar buttons, menu items, etc. you set up the very first time will run the new version without any further action.
