ArtnetTools

Have you tried the Troubleshooting Art-Net Tools page? Go through the steps, and if you get stuck, let us know which step you're stuck on.

all is ok, when i do a tcpdump on en0, i see the art net packet as show on the the page "troubleshooting ..." So i launch QC, after artnet-sender-test.qtz, i disabled artnet-sender. but i see nothing arriving.

????????

A couple of things to check

IP address has to be in the 2.0.0.0 range as well as subnet mask of 255.0.0.0. This is important because most Artnet devices (lighting consoles) don't send 2.0.0.X. Often times you will get something like 2.3.12.34 or 2.1.23.43 for example. This would make sense why the Artnet sender is working but not the receiver. You just need to open up the subnet mask to allow more possible IP address sources to come in.

Hope that makes sense.

ip adress are 2.0.0.21 and 2.0.0.31 and subnet mask are 255.0.0.0 i dont understand where is the problem

Did you check the Structure Key Member patch's Key input? It should match the DMX channel you expect to see values from.

Hmmm I can assure you the plugin works, I use it all the time.

When you put your mouse over the ArtDmx Receiver, do you see a structure? It should be 512 members.

Also, be sure to have some kind of consumer patch hooked up to at least one of the channels, like in the Artnet-SendReceive.qtz example file. Even if that output is hooked up to something like a 3dtransformation patch with nothing in it will make it pass values. Quartz is a strange environment whereas inputs have to be hooked to active outputs in order to pass values through the composition. In Max/MSP values will go as far as they can, even if the results don't do any real work.

I hope that helps

perhaps upload your patch and it might help solving this mystery.

Is the receiver patch actually hooked to anything? It needs to be hooked to a consumer patch to see any values at the output port.
