3:30 this has to deal with texturing, if u have to convert textures it wjll look like this, basically they use blender and convert it with a white mesh, and putted a texture on it. Or they simply bought it in simple town (which where the simple sandbox props assets are used, and constantly having a texture like that)
There's a bug with the Sanbox Cola truck, whenever you steer right or left, if you turn right, the steering wheel goes to the left and turning left the steering goes to the right.
