Quote - Load the gun.  All "props" will load.

Goto Export => Export obj file.

Export the gun as a single object file. (Use select subset to select all loose props)

Delete all.

Import the exported gun obj file .

Duplicate 3 times and you have 4 guns.

Done.

Yea...I just lose the ability to hide the silencer or the flashlight...unless I can maybe do it in materials.  This is the gun, btw, its a nice freebie from FoRender.
