In the next section, you will go over how these packets are sent and received.īy creating an Unreal Engine plugin for DMX which will enable: Each package contains an array of 512 bytes or values that range from 0-255. For our purposes, we are only concerned with the contained data. Each packet is structured in a very intentional way and if you would like to know more about how this works on the hardware level, please read the ESTA standards. Each package is created at some source with specific information that should be received and read by some recipients.
While DMX is primarily used to control lighting devices, there are many other forms of hardware that can be driven using the DMX protocol, including the following.ĭMX can be thought of as a package of digital information that is being sent from one location (our source) to a different location (or destination). DMX can now be used to control almost anything, reflecting its popularity in theaters and venues. It soon became the primary method for linking controllers (such as a lighting console) to dimmers and special effects devices such as fog machines and intelligent lights.ĭMX has also expanded to uses in non-theatrical interior and architectural lighting, at scales ranging from strings of Christmas lights to electronic billboards. It was originally intended as a standardized method for controlling light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. The DMX protocol output and Blueprint nodes can be used to talk to DMX-enabled fixtures and devices, which enables controlling lighting consoles or devices from UE.ĭMX protocol input can be used to trigger live effects or animation sequences within UE that are meant to be displayed on a live show alongside lighting fixtures control.ĭMX is a standard for digital communication networks that are commonly used to control stage lighting and effects. Proper lighting attributes are used for realistic effects so that show designers can iterate in their creative process. Live DMX input is used to drive and control enabled fixtures within a 3D UE level. The DMX protocol can be used in the input provided to Blueprint nodes and fixtures-type actors, for rapid live show stage previsualization. Here are typical use cases that we have identified around the DMX feature. sACN (streaming architecture for control networks), currently appears more popular and allows you to run 63,999 universes of DMX data down a single network cable.
Although it is an older protocol, it is supported by more gear and devices.
Artnet allows sending 32,768 universes down a single network cable. DMX is used throughout the industry to control various devices in the live events industry such as lighting fixtures, lasers, smoke machines, mechanical devices, among others.Īrtnet and sACN are network protocols allowing to aggregate and send DMX data over ethernet (IP). The tools and production pipelines are convoluted, difficult to use, and often impair the overall creation and production processes.Įpic has decided to tackle this problem by adding support for DMX ( Digital Multiplex) data communication through both Artnet and sACN variants.

The existing solutions in the live entertainment industry are a mix of hardware and software platforms that are scattered, proprietary, and expensive. Despite that, it has been adopted by talented groups willing to build the necessary and missing tools/plugins to push the boundaries of the possible further and achieve their desired creative goals. When Unreal was new to this market, it was missing some fundamental and usability features. We have seen numerous executions that have been either partially or totally powered by Unreal. Lately, there has been increasing interest and demand for Unreal in the context of live events and permanent digital installations throughout the world.
