step 5 of 5
first I import both occupation pass and normal pass in Photoshop.after that took only normal pass and do some adjustment by using brightness and contest,color correction and level.
just because to look it realistic.
after that I put that occupation pass on this normal pass..and changed it overlay mode and reduced the opacity...
