This diver scuba rig is a co-production of grinsegold, who made the geometry and myself. So most of the credits are for him. In Blender you should change the materials a bit. Insert the color output of the texture to the glossy shader. For the silver-like parts you can duplicate the material, then delete the fresnel and use a fixed value. In the end you should decrease the roughness of the glossy shader. That's the way the example picture was done. Be aware that parts will deform when changing the geometry or posing the character. You should use this asset with the diver suit. Be aware, that these twin hose regulators were used in the 60s and 70s of the last century.
