A script that allows you to create a copy of any number of geometric objects in Reference mode with a single button.
It can be applied to a group of objects that can be copies, instances of the original object, or have completely arbitrary geometry.

Tested on 3ds Max 2024. It will likely work on older versions.

Usage:
1. Select the master object from which the reference will be taken with the left mouse button.
2. Select the object or group that will serve as copies in Reference mode with the left mouse button while holding Ctrl.
3. Execute the script using the button or hotkey.
4. PROFIT

Installation:
1. Drag the file RefME.ms into the window.
2. Go to the menu Customize -> Customize User Interface -> Toolbar tab -> Scroll Category - select the item kuki-tools. In the Action column, there should be the line RefME.
3. Drag the RefME line to an empty space on the toolbar, and the RefME button will be automatically created.
Finish.

Assigning a hotkey (optional):
For 3ds Max 2020 and later:
Go to the menu Customize -> Hotkey Editor -> Scroll Group - select the item Main UI -> in the search field (above the Action column) type copytransform. The line RefME should appear in the Action column, select it.
Click on the Hotkeys line and hold down the desired keys (for example, Ctrl+Shift+X).
Click Assign.
Click Done. In the pop-up window, click Save and save the hsx file under any name.
