Hi,
I am currently running into an issue in Unity while runnning 4 IntelRealsense D435 cameras at the same time. I have separate licenses for each camera and can run them one at a time with no problem. However, running them together with “Multisensor” toggled I run into the “Nuitrack Trial Time Expired” error after 3 minutes.
Any thoughts or suggestions would be appreciated.
Thanks!
Here is the log. I am just running with 2 cameras at the moment. They show the correct license before I run the tests, but will change to the Pro (License: 5) after the tests throw the “Nuitrack Trial Time Expired” error.
Test Nuitrack (ver.3724) init was successful! (type: Runtime)

@Derrick 1. Try running this sample, does it run for more than three minutes? C:\Program Files\Nuitrack\nuitrack\nuitrack\bin\nuitrack_multicam_sample.exe
Thanks! No, it crashed after a few minutes.
nuitrack_multicam_sample.exe or Unity Demo ?
.exe you sent. I have ran the same demo in Unity before and it crashed as well.
Sorry, I misunderstood. The Unity Sample crashed. The multicam_sample.exe runs fine!
Is the behavior in Unity to recheck the license after so many updates and to apply a trial license on a failed check? I don’t understand why it suddenly changes the key while it’s running. The behavior isn’t consistent other than it not being the first device on the list. Sometimes devices[1]-[3] will all suddenly have PRO licenses attached to them or it’ll just be one of the them. It doesn’t seem to ever effect the camera in devices[0] position.
This is strange.
In general, Unity does not have any work with licensing. Except for the explicit auto-activation on the NuitrackManager component (checkbox and key entry field). But this should not affect you in any way.
Thanks for letting us know, we will try to figure it out as soon as possible and will definitely let you know.
Okay, I’ve burned my eyes looking through the script trying to find what could be causing the error. Have you been able to replicate the error? I was initially under the impression that it must be in Unity since the Nuitrack app works fine. My experience with Unity is pretty limited, so I am learning as I am going. Thanks!
So I have done more testing in the Nuitrack app (outside of Unity). When running the app with:
3 cameras,
AI checked, and
the CSV Recorder checked.
The app runs for only a few minutes and then completely shuts down. The AI subscription keys do not change to PRO. Do you have any idea what could cause the Nuitrack app to force close like it is?
Testing the same environment but only using 2 cameras does not cause the app to close.
Here is a screenshot of the system details:
@Derrick Thank you for informing us about the problem and providing so much information, this allowed us to conduct an in-depth investigation of the problem as soon as possible and we managed to repeat your problem.
We will fix this problem as soon as possible and write to you immediately
