@ SamTherapy Hi, the above procedure is correct. The problem is that most Diffuse maps are wrong.

To get the best results from a Diffuse texture converted into specular and bump map, you have to remove all build-in specular and only maintain the skin (or cloth or prop texture color) variations. => Retain color variation but remove all specular from the Diffuse texture <=.

=> => => But you have to do that anyway for clean SuperFly renders.<= <= <=

In the above example? I did this for the skin but not for the hair as it will be covered by either a prop or dynamic hair anyway. (It only serves some preview test renderings).

Best regards all, and many thanks for the compliments. Tony
