To help add that copper shine seen in newly installed copper roofing, we will add a specular map to increase the specular reflection but varying it to simulate what happens to copper when exposed to air for only a few days.
If you completed the previous recipe, load the copper-turret-04.blend
saved earlier. Alternatively, you can download a pre-created blendfile from the Packtpub website.
We will now add a specular map to our copper material simulation. So, Open the copper-turret-04.blend
, and select the turret object.
From the Texture panel, select the next free texture slot. Create a new texture of type Image or Movie and give it the name
specular-bump
.In the Image tab, Open the file
plating-spec-pos.png
.Under the Image Mapping tab, select Extension of type Repeat and set the Repeat to X
3
, Y2
.In the Mapping tab, ensure the Coordinates are set to Generated and the Projection to Tube.
