Create an artboard that is 800 x 600px. Select CMYK color mode, Screen (72ppi) and make sure that the “Align New Objects to Pixel Grid” box is unchecked before your click OK.
Step 2Create an ellipse with the Ellipse Tool (L). You don’t need to set a size. Just make sure that it is similar to the one on the image below. Duplicate the ellipse (Ctrl +C, Ctrl + F) and move it down with the Down Arrow Key.
Create a rectangle with the Rectangle Tool (M). Place it between the two ellipses.
Create a new, smaller ellipse and place it over the other shapes. While the new ellipse is selected, press the Shift Key and select the other from the top. On the Window > Pathfinder Panel, select the Minus Front option.
Create two rounded rectangles with the Rounded Rectangle Tool. You can increase or decrease the angle by pressing the Up or Down Arrow Keyswhile holding the Left Mouse Button. Place them on the top and bottom of the other shapes.
Select all shapes and press Unite on the Pathfinder Panel. Now you have the silhouette of a UFO.
We need to create a 3D object. We will use the Revolve effect. For this, we need to cut the silhouette in half. Create a rectangle, and place it to overlap the half of the UFO ‘s shape. Select both shapes and press Minus Front on Pathfinder Panel.
Go to Effect > 3D > Revolve and use these values for X, Y and Z axis. Press OK.
Step 9You can play with the values as you want until you get the perfect position and angle for your UFO.
Step 10While the object is a 3D object, you can’t edit as a vector shape, so you need to convert it to regular vectors. To do this, go to Object > Expand Appearance. You transformed the 3D object into a group of shapes.
In order to manipulate the shapes further, you will first need to go to Object > Ungroup (Ctrl + Shift + G). Select every shape and press Unite on thePathfinder Panel.
In some cases, the expanding process results in compound paths that need to be released. To release the compound paths, click on them with theRight Mouse Button and select Release Compound Path.
After expanding the 3D objects, you get some hidden objects which you don’t need. To remove them, select all visible shapes by clicking on them while holding the Shift key. When you’re done, use the Rectangular Marquee Tool (while holding the Shift key), and make a box around the design. Doing so, you will deselect all the items you need and select all the shapes you don’t need. Press delete. If you see that something is missing, go toEdit > Undo, and repeat the selection until you get the correct results.
Another way to get rid of the shapes you don’t need is to select all the visible shapes one by one while holding the Shift Key. Place these shapes to the Clipboard (Ctrl + X), and delete any other shapes.
Now place back everything from the Clipboard (Ctrl + F). Fill every shape with a color. Think about the color of the margins that every shape will have after you use the Mesh Tool (U).
Create two ellipses. These will be the reflections on the “glass cockpit” of the UFO.
After expanding the 3D object, the resulted shapes have lots of anchor points. To use the Mesh Tool, some of the points must be removed. Go toObject > Path > Simplify. Set the Curve Precision to 100% and press OK.
Now you can start using the Mesh Tool. Let’s start with the cockpit. Click anywhere on the shape’s area. After converting a shape into a mesh, you can select its points with the Mesh tool, Direct selection tool or the Lasso tool. Now you can add a color to the mesh. Select a color from the swatches palette, or use the Eye Dropper Tool (I) to select a color from an image.
Select the other shapes and add points and color to them. In this case, add the color white.
Step 17On the bottom part of the UFO, add points as you see on the image and add colors as you like.
Step 18Remember those two ellipses? Fill them with a gradient of blue and set the opacity of the second color to 0% as pictured below using the Gradient Panel.
We’re done with the UFO. Now we’ll create the light rays beneath it. Create two ellipses, and place them below the UFO.
With the Pen Tool (P), create a trapeze by connecting the margins of the ellipses. Select all three shapes and unite them (Unite – Pathfinder Panel).
Fill it with a gradient starting with yellow (C0 M8 Y50 K0), then lightblue (C20 M0 Y0 K0), and finally white.
Create multiple instances of this shape, rotate them and place them so you get a light ray effect. I found this free Jumping Cow vector file, and I thought it would be perfect to use on the final image.
