Hi,

I am trying to integrate leapmotion sdk v2.3 with oclus rift in Unity 5.5 , and find that leapmotion disable oclus once I add the dll into scene. There is no error message , oclus just does not work once I import leapmotion v2.3

And Oclus work with leapmotion 3.x well, but not with 2.3. I am using leapmotion v2.3 instead of orion 3.x because I need tool tracking.

Any clue ? Anyone did this before? I believe it is pretty common use case

What version of the Unity assets and the Oculus SDK are you using?

I am using Unity Assets of 2.3.1 downloaded here https://github.com/leapmotion/LeapMotionCoreAssets/releases/tag/v2.3.1 in Unity 5.4 and 5.5, which has built-in oculus VR support, so I am not using Oculus SDK explicitly, just using the one released with Unity.

And I tried not using any Unity assets, just an empty scene with VR mode enabled and LeapMotion v2.3. Once the leap dll is added into the project, oculus does not work.

The old Unity assets are built with the old Oculus plugin, which was deprecated in mid-2015. That would be the source of the issue.

Hi Alex,

I am using leapmotion sdk v2.3 because I need tool tracking, which is deprecated in v3. . I tried to use latest version of Unity Assets and it did not work, I guess it could be version conflict issue, so I tried Unity Asset v2.3, the save version as LeapMotion SDK, it does not work either.

Then I did another try, not using any Unity Assets, just create an empty scene and add LeapMotion v2.3 dll and it disable Oculus VR as well, so I dont think it is due to Unity Asset.

Is it possible to enable tool tracking function in LeapMotion SDK v3? Why took tracking is deprecated? I am trying to use Oculus VR＋LeapMotion tool tracking, and I believe it is a pretty common use case.

Thank you for help.

Unfortunately it's not possible to enable tool tracking in V3, as the tracking software underwent some major changes between versions. Tool tracking was dropped in part because it made the hand tracking more reliable and allowed us to better optimize our tracking performance.

To be honest, we didn't really see much tool tracking used in the context of VR. For instance, among the hundreds of projects submitted between the two 3D Jam competitions, I don't recall any using VR + tools.
