A fog effect is supported, with control over the distance from the camera where the fog starts, and the distance from the camera where the fog completely obscures the view. Rendering controls are easy to set, with a frame in the Perspective window graphically showing what will appear in the rendered artwork, and simple dialog settings to control resolution. The program estimates how long a given rendering will take based on image complexity, resolution, and renderer settings. The program can create an alpha channel to isolate objects in the scene from backgrounds when a rendered PICT file is imported into Photoshop or another program. Anti-aliasing is supported.
Documentation is readable and thorough, with good basic and advanced tutorial projects.
Free technical support is available during the day via a toll call, or through the internet and online services. There are a few criticisms I could make about this program, but not many. If you don't need to do animation, and want a 3D program with accessible features, check out Ray Dream Designer. For the money, it can't be beat.
