Here is what I do. It is kind of a cheesy quick way but always works for me. Select the object that you want to map. Click the edit materials thing. Go to miscellaneous and turn on the steel cage material. In the grid block (section a) load the transparancy map. In the greyish block (section b) load the material and bump if there is one. Change specular highlight to something that is not light blue. Should match the item in question bascially. Alter bump if need be and viola ... you are all set ... Good luck
