Add another Layer with the following settings.

Okay, just one more and we’re done with the Colour Channel! Add another one with the following settings
Picture 170: The Sixth and last Layer in the Colour Channel
Now, all these Layers will create variations in the colour for our material, a test render at this point should look something like picture 171.
Picture 171: A new test render
Since the opacity of the layers we just added are all quite low, you wont notice much difference, but that’s just fine, we don’t want heavy colour variations.
Lets add some dark variations as well. Click the T for the Diffuse Channel and use the following settings.

That’s it for the Diffuse Channel. Next we’re going to add some variations for the specularity. Click the T for the Specularity Channel and use the following settings.
Picture 173: The Texture for the Specularity Channel
That’s it for the Specularity Channel, click Use Texture when you’re done. Now, for the Reflection Channel we are going to use another Gradient Map. We are going to use the same technique as with the glass earlier, where the polygons of the object will reflect less as they turn away from the camera. Click the T for the Reflection Channel and use the following settings.
Picture 174: The Gradient Map for the Reflection Channel
The Top Key should have the following settings:
Value: 100%
Alpha: 100%
Parameter: 0.0
And the Lower Key should have the following settings:
Value: 100%
Alpha: 0%
Parameter: 90
Click Use Texture once you’re done. A test render should look something like picture 175 at this point.

Note that the material will look dull until we choose to raytrace reflections. This will take some more rendering time so I’m keeping it turned OFF for now. Lets add some bumps to this surface as well, so click the T for the Bump Channel and use the following settings for the first layer.
Picture 176: The first Bump Layer
Add another Layer and use the following settings.
Picture 177: The second Bump Layer
Add a third Layer and use the following settings.
Picture 178: The third and last Bump Layer
The last Layer we added here will create more drastic holes in the metal, as if the metal was damaged. That’s pretty much it for the Metal surface, and our Lantern is now fully textured and ready for some rendering.
Open up the Properties Panel for the Camera and turn Anti Aliasing on, I’m using Enhanced Medium. I’ll be rendering this in 1024x768 but you can choose which resolution you want. Further on, in the Rendering Options Panel, use the following settings.

Also, make sure you choose to save the finished Render in the Output Files tab. That’s it, press F10 to start the rendering. This will take some time due the reflections in this scene. I hope you enjoyed this Tutorial and I wish to thank you for reading it! Picture 180 shows the Final Render!
