Controlling an addressable LED strip using the Art-Net Mapping node
Description
The Art-Net Mapping node in the FX Graph module can be used to transform video content into DMX data. In this example, we will use the /line_generator/ node to generate content that will be mapped on the LEDs. You can use any video source, real-time or playback, as long as it has the same resolution as your LED setup.
RGB LEDs need three DMX channels per LED. This means you can control up to 170 RGB LEDs per DMX Universe.
