Hello. I have been trying to add lights to this unlocked vehicle. All I want to add is a beacon to the car. I successfully got the vehicle into ZModeler3 with no problem, but when I add the beacon, it doesn't show up in Zmodeler, nor do I know how to add the textures that are in the folder.
I am getting this error too: http://prntscr.com/cee6pi (See Screenshot)
