# Troubleshooting Orbbec Model Files ## Required Files & Directory These are the critical files for skeleton tracking to work: * `dnn_model_2_0_op11.onnx` * `dnn_model_2_0_lite_op11.onnx` Make sure these files are available where the app expects them to be. Since the logging from the `CaptureManager` and `SkeletonProvider` aren't helpful, try adding those files to the following directory: ``` C:\Program Files\Azure Kinect Body Tracking SDK\tools ``` To get past this message in the logs: > [!error] > *Cannot initialize Azure Kinect Body Tracking runtime.* > *Make sure that there are the following files in Assets\\Plugins\\K4AdotNet folder:* > > *1. k4abt.dll* > *2. dnn_model_2_0_op11.onnx* > *3. cublas64_11.dll* > *4. cublasLt64_11.dll* > *5. cudart64_110.dll* > *6. cudnn_cnn_infer64_8.dll* > *8. cudnn_ops_infer64_8.dll* > *10. cudnn64_8.dll* > *11. cufft64_10.dll* > *12. onnxruntime.dll* > *13. vcomp140.dll* > > Assuming these files are in place, it *should* work. I needed to do the following: 1. Install `Azure Kinect Body Tracking SDK 1.1.2.msi` 2. Install `Azure Kinect SDK 1.4.1.exe` 3. Add the ONNX model file to the directory mentioned above After the final step (found by trial and error), the skeleton tracking functionality started to work. #unity #orbbec #kinect #motion
