Strobe

The Strobe layer creates a flashing strobe effect over multiple screens.

Warning: The Strobe layer only works using a Feed map. In order to turn each screen into "one flash", scale each feed rectangle to 1 pixel and place each screen's feed rectangles next to each other on the Mapping canvas.

Some Generative layers take their source from other layer types - either content or generative - by use of an arrow. Linking two layers with an arrow defines the arrowed from layer as the source, and the arrowed to layer as the destination. If you have an arrow between a content layer and effect layer, it is said that the content layer is being 'piped in' to the effect layer. For more information on arrows, see the compositing layers topic.

To draw an arrow between two layers, hold down ALT and left click & drag between the source and destination layer.
