2. On the front page are a number of archives you can download. I felt the Factory Catwalk images seemed
most appropriate for this character. Click on the Factory Catwalk icon to download a zip file containing

You can import jpegs and HDR (high dynamic range) images into ZBrush to use as backgrounds and for
image-based lighting. High Dynamic Range images contain many levels of exposure, which is why they
are often used for image-based lighting in 3-D applications. However, you can get good results using a
jpeg as well, and the render will be a little faster.
