Before starting with unity … I would suggest you first get the sample in the runtime working.
The error you are seeing is because nuitrack can’t locate the files it needs.
The sdks and the runtime are different packages … You need to install both ideally.
First start with the realsense sdk … Download it from Intel … 2.15 is the release that is matched to nuitrack … Download and install this …
Run the realsense viewer … It will likely tell you to update your firmware …
Do this first … As Intel ships old firmware.
You should see an image and such from the sensor.
Make sure also that the viewer reports a connection to USB 3.0 or preferably USB 3.1. … Nuitrack requires this … Not USB 2.0.
Next the nuitrack runtime … Download and unpack into a folder path that had visibility to all users … Do not unpack it to your desktop folder or user folders.
I would suggest C:\nuitrack\ is best.
Then make sure the permissions on the folder allow everyone full read write execute access.
Then set the environment variable and the path as described in the install notes … Again making sure that you set these to at system level not user level.
If you have unpacked the runtime correctly the environment variable should point to
The path should be set to
There should also be a data folder and an activation folder in there.
Go to the activation folder and run the nuitrack.exe … It will let you test if things are setup correctly.
If everything is good you should see an image from the sensor during the test
Now download and install the nuitrack sdk … And again put it in a public path … C:\nuitrackSDK\
Now you should be setup to start testing with unity.
