Does the flying saucer that comes with this bundle include the effect shown in the promo images?
Or do I need another product to create the light beam effects reaching down from the saucer?

They may be popstwork, image editing done after rendering, but if not you could probably achieve the second at least with a cone primitive (Create>New Primitive) given rduced opacity and soem emission (in the Editor tab of the Surfaces pane). I'm pretty sure the first one has a spot-light almost directly behind the figures to give the rim effect, the beam might be a cone with a map applied to Cutout Opacity or translucence but it might also be an effect with the foreground figures having been rendered separately to generate a mask that could hide the parts behind them.
Thank you Richard!
I will try your suggestion. But I also have the Ghost Lights for Iray product

which has a column type spot light and haze effect, so that might work too
Yes, probably - or it may be something like one of Jepe's effects (or similar - several people have done effects products using images on a plane or set of planes), on a plane or a cone.
