Creating your own specular maps is a much better practice. I would render an ambient occlusion map in xNormal and overlay my UV layout on that in Photoshop/GIMP/whatever, then paint my specular map on a new layer(s). You can blend in the ambient occlusion map where needed too that way. Good luck.

I was really wondering if you can create specular maps in xnormal? I have seen a tutorial on how to create a specular map from a bump map in photoshop,…
