I came up with a flow chart for you to try and show how to apply your texture to different options, like Color Map, Normal Map and Spec Map. The Spec map can be difficult to see unless you have a light reflecting off of your object at just the right angle. The sword is looking pretty good. I'd almost bet that the dark spot on the tip may be from a surface normal facing the wrong direction. Hope this helps. Texture/Material chart
