Instructional Video (TBD)

1. Install the JSONLiveLink plugin for Unreal.

   1. Create a new UE project, close the project.
   2. Create a Plugins folder in the project folder, and copy JSONLiveLinkfolder into it.
   3. Open the project, the project will be automatically rebuilt.
   4. Make sure the plugins Live Link and JSONLiveLinkEnhanced are enabled.

   

   1. Open the Live Link window ( Window > Live Link ) and add the JSONLiveLink source (specify the ip and port).

   

2. Drag and drop JSONLiveLink.tox into the TD.

3. Create a UDP Out DAT for it and specify it, and set the port parameter to be the same as the JSONLiveLink source on the UE side.

   

4. Confirm the type of Role you want to use and press Create Subject. The Live Link window on the UE side should show its subject.

   

5. The usage after that is the same as other Live Link plugins.

• To control camera parameters in UE 4.27, the LiveLinkCamera Plugin needs to be enabled.

• Scale doesn't work in UE 4.27. Fix.
• Once a Subject is created, the UE side cannot change the Role type anymore.
• If a Subject is deleted on the UE side, a topic with the same name cannot be created again.

The above issues need to modify JSONLiveLink plugin itself to solve.
