A slightly improved script by Tom Shannon (previously named TS_UE4FBXExporter).

• Tested with UE5.
• Added sanitizing for illegal object symbols.

What’s it let you do?

• Export each selected mesh to an individual FBX file
• Move each mesh to 0,0,0 for export (Then put it back where it belongs when it’s done like my kids NEVER DO!)
• Name Each FBX according to the MAX scene name
• Allows you to use a grid object to set an arbitrary origin (For really big scenes)
• Just make a Grid helper and name it UE4_Grid and the script will detect it
• Copy the location, position and scale or selected objects to the clipboard using Unreal-friendly syntax allowing you to paste thousands of objects objects into your UE4 maps with a couple of clicks!
