Yesterday I talked about how to get that low-poly effect but a few of you emailed me questions as to why the Sphere Object was not rendering in low-poly, even after you followed all of the directions. One option is to make the sphere editable, however, there is a setting on the Sphere Object called Render Perfect. This setting renders the sphere, no matter how few polygons or subdivisions, as a perfect sphere. Even with your Phong Tag set to zero, or removed completely, it will still render perfect spheres. Simply uncheck that box and you will be good to go without having to make your sphere editable. Here is an example of how it works.
Please feel free to shot me an email or comment on any tutorial if you get stuck or run into a roadblock. Enjoy!
