No, I can see the specular happening there. It's not very obvious, but it is definitely shinier than the triangular sections in the middle.


Okay, I forgot to mention - I changed the sun color to 255,255,255
Also, you may want to increase the "power" of your mtl_specBump material. You can modify it in mtlFX.c, or create a new material, like the one I posted in your own script. Just make sure to assign the new material to that object in WED.

The manual mentions that power can be set between 1 and 10, but I think it can go up to 100 and it gives more shininess as you go higher.
