TouchIn/Out DAT Multicast Problem

General TouchDesigner Discussion

Hi!

I’m having a problem with sending data between two machines with TouchIn/Out DAT using the “Multi-Cast Messaging (UDP)” protocol.

I can see that the data on the reciving machine using Wireshark but Touchdesigner does not receive the data.

Does anyone know what the problem could be?

For multicast, make sure to send to an address in the range 239.255.0.1 - 239.255.0.255, (so not to the actual IP-address of the receiving machine) and then set the addres in the TouchIn DAT to that same multicast address.

Also see docs about multicast here: Network Protocols - Derivative

@nettoyeur, I’m still having the same issue. My computer that sending the data have the IP of “192.168.8.151” and the reciving computer have “192.168.8.123”.

Both TouchIn/Out DAT have the protocol set to “Multi-Cast”, network address set to “239.255.0.1” and a port of “9500”, and I’m still not getting any data into TD. But as I said before, I can see the data on the reciving computer but only on Wireshark.
