So now I've got my hat with three segments with curves from my last Beginning Blender article. I will admit that I cheated a little bit, ignored those other Bezier curves I created and ended up simply copying the original diced-up segment of my hat. So let's finish the job and make this thing a pirate's hat.
I need to make the outer sides of the hat more vertical. So I start selecting the points on the hat that I want to manipulate. To make things a little easier on myself, I use Box Select (B on my keyboard) to select the ones I want. You can actually use a series of Box Selects in cases where you can't get all the vertices you want in one box without hitting the ones you don't need selected right now.
Now the points I want to modify are selected and I can manipulate them as I need to. In this case, I rotate the points along the Y axis, grab it and move it up a tad so that I don't distort the points where this side is connected to the hat too much, and then rotate it along the Z axis to get it better lined up. I've gotten my sides moved around so that they're more steep.
But now you can barely see the obligatory dome that makes up the top of the hat. This is going to be heinous to deal with if I don't do it exactly right, so what I do is use the Box Select tool to select its faces in segments. This takes some experimentation: Moving it up along the Z-axis with the Grab tool, and then Scaling it to make it bigger. I also Scale it along the Y-axis to make it just a little bit more oval-shaped. Once I tuck in a few points that were sticking out, it looks about where I want it.
Now that the dome is in shape, I go back to the sides. My aim here is just to smooth a few things out, so I select faces along two of the sides of my hat and move them up so that they're more in line with the main sides.
That's a little better, though this is probably never going to be perfect. That thing's going to be a tad big for our pirate captain's head, so for one last thing, I Scaled the whole thing down so that it's a reasonable size.
Now what I want to do is add some color. This won't show up until I actually render my hat, but considering that I just want it to be black with a little white around the edges, all I have to do is find the Color Correction options in Blender. So I go to Object Mode, take a look at the options on the panel on the right side of my screen and click on the “Materials” option.
First, I want to make sure I have at least one Material in the list on top of the Materials menu. If I don't, I click the plus sign button next to this list to add one. Then, I go down to the Diffuse options, click on the white bar to get the color wheel, and adjust the grayscale to my liking (in this case, as white as possible). What diffuse does is determine the color an object will be when a light is shined on it. For instance, if you shine a white light on an object that is green, it will only reflect green light. If you don't want your hat to be pure black, you can pick any color on the wheel or add whatever level of grayscale you like. I do get a bit of a preview here so I can see how this will affect my hat. I can also adjust the intensity of the diffusion to my liking.
Then, I go to “Specular” and adjust the grayscale there. This basically adjusts the “shiny” quality of my hat. I set both Diffuse and Specular to White and also set the Intensity to 1.000 to enhance them.
So much for Object Mode. I unselect the hat and then go back to Edit Mode. I've adjusted my diffuse by just a tad so that I can see the individual faces. When I try to select a face and adjust the diffuse and specular to change its color, it affects all the faces. Obviously, that is moderately unhelpful when I just want the edges to be white and the rest black. What to do?
The obvious thing will be to add a new material. So I unselect the face, go back to the Editing panel on the right side of my screen, add a new material by hitting the Plus sign, and set the new texture's Diffuse and Specular to black, so that my materials look like this. My Textures controls should now look like this:
Now I right-click on a face to select it and go back to the Editing panel. Because I want most of my hat to be black, I hit B for the Box Select tool and start by selecting faces in the center of the hat. Then, I go to the Editing panel and hit Assign to add the second material to the selected faces. Here you can see what I've done so far:
Put It On His Head
I've got something that vaguely resembles a pirate hat, so let's put it on our pirate's head. I hit M to move it between layers, which pulls up a dialogue box that I use to choose the layer. This causes my hat to disappear from Layer 2. No big deal; I just move to Layer 1, grab the hat that looks like it might be a little uncomfortable to our pirate where it is now, and move it up to his head. That's too small, so I Scale it so that it's a bit bigger. And now my pirate has a hat.
