Art-Net
Art-Net universes are enumerated from 0, so first Art-Net universe is 0
You must have at least one Universe set to Art-Net, to be able to enable it. When enabling Art-Net, ideally, do not change the IP address settings and leave it at the default 0.0.0.0 .
Enabling Art-Net
Create Universe, set it to Art-Net, enable Art-Net Input:
Note: Art-Net Input can only be enabled if you have at least one Universe set to Art-Net
Using a console on the same computer
When using an Art-Net source on the same computer, you have to make sure to start and enable Art-Net first in the BlenderDMX.
If running two pieces of Art-Net based software on one computer is not working for you, then save yourself the trouble and the best is to use another computer for the sending.
Checking who/what is using the Art-Net port
On Linux (and perhaps also on macOS) one can check what program (PID/name) is currently holding the port 6454 open, blocking it. This can be checked by running the following command in the terminal:
netstat -aop | grep 6454
