This is the 3D model of the trailer that I created within cinema 4D I exported it as an FBX so that unreal engine can read it. To create this trailer i used a standard box and extruded it to give it depth. after doing this i used the torus to make a metal chain on the side of the house. The dirty rag on top of the trailer is a cloth that I simulated within C4D and then paused it on the scene that looked best.
