It might be using the wrong texture. Poser has the unfortunate habit of grabbing the first texture it finds with the right name. So you may end up with the black Millennium Cat texture applied, when you wanted a black dress texture, if they are both named "black.jpg." Now most people use unique names for the texture maps, so it's not a problem, but the antelope is old enough that they might not have done that.

The way to test if this is the problem is to rename the texture you want to something unique, then apply it manually, and see if it looks right then.
