Setting up ultraleap, hand tracking is not working

[raby-dot]

Hello,

I have a problem with setting up ultraleap in unity. I followed the getting started with unity steps.

Ultrahaptics device connected and tactile sensations are felt but ultraleap hands tracking is not integrated. In unity, ultraleap category can be seen. However, when ı put the service provider and hands from this category, it is not tracking my hands. Device is working without unity, demo is working but examples also give error in unity plugin from github. I didnt find a help to solve it.
I set up sdk from ultraleap github plugin, also ı added the scope to the project manager and activated, but still hand tracking is not working. There is no problem with tactile side. The error is that service provider is not working. How can ı adjust ultraleap hand tracking with unity.

Which version of the hand tracking service have you got installed? Which hand tracking hardware - e.g. Leap Motion Controller, Rigel / SIR170, 3Di, Leap Motion Controller 2? Which version of Unity are you using and what plugin version? What operating system are you using? Do you see the plugin attempting to connect in the console log?

Leap motion controller Orion 4.00+52173
Unity 2020.3.27f1
I added leap motion to project manager from ultraleap documentation site.
[name:Ultraleap
URL: https :// package.openupm.com
Scope: com.ultraleap]
In package manager, ı installed 6.00 version bc there was only this option.
when ı attempted running,
Leap service provider is the problem ı guess

OK, if you are using Orion and Unity 2019 you'll want a much older version of the plugin than V6. Likely the LeapC client dll is too new to work.

[MaxPalmer-UH]

Try something like V5.9 which was the last release to officially support Unity 2019.

Ok ı will try this version, thanks.

Just download the release .unitypackage and import that rather than using the package manager

In this site some links doesn’t work, so ı didn't find exactly which sdk ı should add

[MaxPalmer-UH]

I would start with 5.9 on the releases page. I can't remember at which point we updated the LeapC client.

[MaxPalmer-UH]

If that doesn't work, go back to 4.6 ...
