For this tutorial, we created the artwork for the box in Photoshop that we’ll apply to a 3D object in Illustrator. The art consists of three separate flattened PSD files that we’ll place in Illustrator. The file for the front of the box is 5×5", and the files for the sides are 3×5". (Note: For this tutorial, we’ll only be using the front and right side of the box artwork.)
