This diver suit 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 weights 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. Delete groups are used, only face and hands are left. Be aware that the weights deform when changing the geometry. An additional material is available. Use this asset with the diver scuba rig.
