This very simple script was made to easily copy/paste objects from one scene to another. For example if you're working in a scene but want to do shaders in another.
Just write the script in your MaxScript editor, mark the text and Drag&Drop it into any toolbar where you want it and voila, you have a button.
Copy code (change URL to whatever you want) or just use the attached scripts :
(
saveNodes $ "C:\\3dtemp\hej"
)
Paste code:
(
mergeMaxfile "C:\\3dtemp\hej.max" #autoRenameDups #renameMtlDups
)
