GOBOs

Gobos are images mapped to a lights color channel that creates a stencil or blocking effect. Gobos are a quick way of adding shadow effects without have to actually build model to cast the shadows. In this image the top gobo, the window, effect shows the render and the image that was used. When you assign and image to a light's color channel a new attribute tab will appear; the stencil, this is where you make most of the adjustments affecting that appearance of the gobo. The settings shown, particularly the mask settings prevents the light's cone from showing (square image over a circular light). You think of gobos without doing the bat signal or menacing shadow in a doorway so I've included these example also.
