In the previous part I have showed you some basic directions toward making the surface that we are going to texture, this time we will create something very common in metal textures, the rivets, that can be turned into nails, screws, etc...below is an image of some of them I usually create for my textures, as you may notice the process is quite the same, although the environment chages a bit and that you must pay attention , because if a rivet is in plastic wich has sand, it won't be that shiney and its color will have some of the environment color.
Take a look at the image:
As usual to soften down the shadows we will feather the selection a bit again , if you havent understood why i keep using the feather option, take a look at the image below, you will see that the circle is much more soft thou not very exagerated on the right , thats the effect we want for shadows.
This step is the most important in my opinion because thru the burn tool ( set in highlight mode as well with around 30 or 40 opacity - you decide- ) we will make the bottom shadow of the rivet, dont forget, make it all in the circle, but dont forget the lightsource , this means that the area below right will have a more quantity of shadows on it.
The dodge tool also makes wonders, doesnt it ? we select it and set it to highlights too, in order to bring up the higher tones with more realistic look ( around the same opacity as burn, it really doesnt matter ) and we paint some of it in the place of direct contact with the light, therefore it will be wide.
I just deselected the image to be easier for people to see the general effect , but after your done with the previous step , you will add another highlight on top of the previous ones, preferably with a smaller brush and maybe the same, a bit lower itensity
At the right side of the highlight we will make another highlight using the same process, although note that this one is smaller althou more curved to follow the sphere shape
Now it's the time to darken even more the shadow at the bottom, but very subtly, to make the sphere gain height
This step should be added at the end of making this, but since the surface is simple wwe can make it now, you will get the dodge tool again, and will set it's option to Midtone instead of the highlight, and with a small brush too, you will paint a stripe following the spheres direction too, but at the bottom, NOTE THAT ACCORDING TO
THE ENVIRONMENT THIS RIVET MUST HAVE THIS DETAIL COLORED THE SAME TONE (example, in s red metal, this detail will get redish, and so on)
Like we did with the part 1, we will get the feathered selection again and invert it, in order to paint a shadow below the rivet (do not use layer effects, painted by had is better because you have more control and can deform the shadow if you want the way you want), and make that shadow with the burn tool in the metal, again, follow the lightsource and paint it below.
And here it is, quite simple isnt it? Remember that my rivet seems a bit blurry because the lightsource isnt very sharp , in order to fix this add more shadows to the bottom and make highlights more bright, do it as you like it wont mess what you created so far.
In the third part, where we will learn how to make a realistic hole in the metal, wich is EVEN EASIER than this wich we have came so far ;)
