blank normal, specular, and shadow maps for clothing meshes?

I've been working on some new clothing meshes and I need a blank normal, specular, and shadow map to get rid of the existing ones. It is for a dress, so i cant move it onto a nude mesh which has everything already empty. last time i tried to use the maps from a nude mesh on the dress, it screwed something up and i had to make a new version. its the only thing I have left to fix on my mesh, so it would be much appreciated if someone could help me :-)
