OK, I have to add something in here that I missed earlier, as missing it can mess up your results. The specular map needs some careful preparation in PhotoShop or whatever image editor you use, or it can spill over into areas that should be transparent. As was pointed out earlier in this thread, specularity in Poser does not normally respect transparency at all. To force it to do so you need to add the transparency map you are using to your image as a layer, above everything else. Chnage the layer blending mode to "multiply" and then save the specular colour map. To make the change clear I will add images of the last version and the updated one below. Here is a trio of Victoria 4s wearing Radiant Jaguar Hair with the latest versions of my copper coloured maps. You can see the highlights change as the lighting changes.
