I appreciate the kind words. If there is anything you need please don't hesitate to ask. I started off knowing really nothing about scenery design and became knowledgeable over trial and error. It probably doesn't help that I am a perfectionist when it comes to modeling and textures. :rotfl:
I generally make two Bitmaps. One Specular Map and one Diffuse for the base/stain. Then I use the "Blend Environment by Specular alpha" and tune the reflection with the numbers in MCX. I will download your image and take a look.
