Azure Kinect for Unreal Engine

This for of Ayumu Nagamtsu's plugin für UE4 enables using the Azure Kinect sensor in Unreal Engine 5.

Prerequisites

• Platform: Win64
• Dependencies:
  • Azure Kinect SDK v1.4.1 is expected in the default installation directory. If you are using a different one, provide its absolute path in the AZUREKINECT_SDK environment variable.
  • Azure Kinect Body Tracking SDK v1.1.2 is expected in the default installation directory. If you are using a different one, provide its absolute path in the AZUREKINECT_BODY_SDK environment variable.
• Unreal Engine 5.6+
  • Tested with Unreal Engine 5.6.1. May or may not work with previous versions.

Usage

• Install the prerequisites.
• Clone the repository into the "Plugins" directory of your project.
• Restart Unreal Engine and check the plugin list for "Azure Kinect for Unreal Engine 5".
• The UAzureKinectDevice is the core class implementing all the stuff.
• The BP_AzureKinectActor in the plugin's content shows how to put everything together. It uses a default instance of UAzureKinectDevice called DefaultAzureKinectDevice, also located in the plugin's content folder.
• You can double-click the DefaultAzureKinectDevice to test the setup:
  • Attach the Azure Kinect via USB.
  • Click the "Refresh" button at the very top of the device configuration. This should populate the "Device Selection" list below with the serial number of your device.
  • Select the device and configure its behaviour.
  • Click "Start" in the "Camera control" group at the very bottom.
  • The "Start" button should change to a "Stop" button, and you should start seeing updates in the previews of the textures configured above.
  • If nothing happens, that is if the "Start" button remains, the device was not found or could not be started. In this case, make sure that you have selected an existing device in the dropdown at the top and check the "Output Log" for messages.

Debugging

Logging can be enabled for the Azure Kinect SDK by setting the K4A_ENABLE_TO_TO_A_FILE environment variable and setting the K4A_LOG_LEVEL variable to one of 'c', 'e', 'w', 'i' or 't'. There are similar, but undocumented variables K4ABT_ENABLE_LOG_TO_A_FILEand K4ABT_LOG_LEVEL for the body tracking SDK.
