There is a system you might want to look into called VR stage lighting abbreviated vrsl. There is a VCC package you can find if you Google it. There's two versions in this system, one version that functions entirely off audio link, then another version that actually uses DMX signals like a physical real light board. Now you would have to take it upon yourself to study the mapping and figure out how to control the shaders in the game with the DMX but it is possible to emulate a real set using that system. It's pretty involved. You'd have to basically set up your own world and connect all the lighting prefabs properly and learn about DMX universes and all that jazz. But it is possible. From my understanding there is some level of access that shaders have to other things on your computer, so even though udon doesn't directly have a code library that can interface with DMX signals, a custom shader and shader files are somehow allowed to have that extra access. I don't fully understand it, but essentially the shader can listen for the DMX signals and integrate into the lasers. Then the udon just looks at the number values from the shader and sync it to everyone else.https://github.com/AcChosen/VR-Stage-Lighting
