Visualizer Help?

Hi, It could be just me, but I think the directions for the visualizer and capture are rather lacking. I can’t connect Capture to Beam because Capture 2021 doesn’t give me the option of ArtNet under external universe. Any ideas?

Hi Gary,

While we have been aware of this issue, your post led us to investigate this further and start working on some improvements that should make connecting to visualizers and other Art-Net applications running on the same computer more user-friendly. So thank you for reaching out - that’s very valuable feedback! For now:

  • In order to send (unicast) Art-Net to Capture via the loopback address, Capture must be started before Beam.
  • Alternatively, you can send Art-Net to Capture by specifying a broadcast IP address as Art-Net output in Beam - then the order of execution should not matter (though keep in mind Art-Net packets will be sent to all the devices within the same subnet).
    You can read about broadcasting here and use a tool like this one to find the broadcast address.
    On macOS, your IP address and subnet mask can be found by going to System Preferences → Network → select the relevant network interface → Advanced → TCP/IP. If your IPv4 address is and subnet mask is, the broadcast IP address will be

Please share if the solutions above work for you. We will also add a note about this in our manual.
Besides that, as Capture is software developed by another company and a universe on its own, we only provide the instructions necessary to run the demo set, get you started as quickly as possible, and merely suggest it as a good option for lighting visualization.
If you are interested in learning Capture in-depth, their video tutorials and the Reference Manual are a good place to start.
With this in mind, if there is anything else specific about the Beam <-> Capture workflow that you think could be better explained, please let us know.

Hope this helps!
