One of the textures in this set has s specularity map.  The program did not convert it from the CR2.  I had to apply it the the texture map of the material file, save a new CR2, and do another conversion to get the specularity map.  The new MAT file was just the texture and bump map with no other shaders.  I ended up having a Poser document with both V4 and Dawn so I could apply the original texture to V4 and copy her nodes to Dawn and then replace the V4 textures with the new Dawn textures.

I had thought the program would convert the shaders, but it makes sense that it doesn't since it saves a MAT pose file rather than a material file.
