In the following tutorial, you will learn to create a simple flying vector UFO in Adobe Illustrator. Using 3D effects and Gradient Mesh, you will learn to create this piece with realistic effects.
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.
Create 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.
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.
