Fix for UE 5.5.3 OSC/VMC receive IP not working for 127.0.0.1

[The-Chilli]

There's a bug in UE 5.5.# where the OSC server will not receive local OSC messages when IP is set to 127.0.0.1, which is the default for this plugin.

Fix: Edit the "Receive IPAddress" Variable in /Actor/Latest/Sub/BP_VMCReceiver and change from 127.0.0.1 to 0.0.0.0 when using a local OSC sender like XR Animator. Compile & save the blueprint. Double check any instances of the receiver in your levels, also have 127.0.0.1 changed to 0.0.0.0

The Widget for the WBP_VMC called "UW_VMCInfo" also has a "Create Server" node (Target BP_VMCReceiver), which also needs changing to 0.0.0.0

Using the Editor blueprint /Actor/Latest/WBP_VMC should now also display incoming OSC messages from localhost/127.0.0.1

Hi. Thanks for the report. I will fix the IP address specification for Blueprint.

However, OSC reception using this BP is an old implementation. I recommend to use AnimNode to receive OSC in the new plugin.
