Azure Kinect DK only work in CPU mode with Unity / Visual Studio

Question

Only works with TrackerProcessingMode.Cpu but not TrackerProcessingMode.Cuda or TrackerProcessingMode.Gpu, however the stand alone app : Azure Kinect Body Tracking Viewer works with k4abt_simple_3d_viewer.exe CUDA

Have tried rolling back to old versions of SDKs, CUDA, Unity with no change of results checked all require files are part of Unity project in correct locations. Also tried adding C:\Program Files\Azure Kinect Body Tracking SDK\tools to Environmental Variables and running the Unreal project file with not success.

Hi @Andrew Banks ,

As per the related thread on github: https://github.com/microsoft/Azure-Kinect-Sensor-SDK/issues/1682#issuecomment-1147305310

@fkavache "Check the latest changes in the unity samples project. Please follow the updated instructions."

And you confirmed that is now working:

"
Many thanks fkavache this is now working! One note for those installing the MoveLibraryFile.bat file did not copy the below files so have to do them manually :
directml.dll
onnxruntime.dll
onnxruntime_providers_cuda.dll
onnxruntime_providers_shared.dll
onnxruntime_providers_tensorrt.dll
"

Thank you!
