This is a simple effects test animation to see how well the Hash Inc. Animation:Master glow effect holds up in a sequence (a feature added back in 1998). This specific material look is achieved by having the object being partially transparent, highly ambient, a default dent texture, and two bright lights producing large specular highlights on the object surface - the object glow attribute does the rest. Sky is a digital photo used as a background template (camera rotoscope), which works fine as there is no camera movement in this shot. Saucer movement is through a simple path with a secondary wobble action overlaid.
