This model has been created using blender 2.79 and uses both subsurface modifier (set to 1) and bevel edge modifier. The FBX and OBJ files have been saved both with modifiers applied (filename...sub1) and without modifiers applied.
Textures are provided as both grunge and basic in jpeg format. maps include (base color, metallic, height, roughness, normal). Both sets of textures use the same naming structure.
For those who use Blender, there are some basic control empties for moving the handle and head of the jack etc, but this is NOT a rigged model.
