    Why did your version of the plugin get dropped for the new one which is decidedly worse?

    Why is this the standard plugin, when the previous plugin was much better?

    Specifically https://github.com/getnamo/leap-ue4

    Had better commands, better hand models.

    Anyone interested in bringing that version back up to compatibility with 4.23+?

    I started this leap motion "journey" downloading the lastes vesion
    available:
    4.22 plugin. I'm having some problems finding the plugin in Unreal, I can see only "magic leap" plugin in the plugin setting, that is not leap motion plugin. I put the Plugin folder in my project folder and i did the lip motion tryal in leap motion control panel, everyting seems ok with it.

    I can't understand how to activate the plugin in Unreal.
    Thank you in advance.

    The engine plugin is disabled by default, but you should be able to enable it by going Edit->Plugins and then selecting the category Input Devices. In there you'll find the Leap Motion Plugin tick enable and restart your project to see it loaded up.



    Optionally you can install it as a project plugin by getting the latest release from github e.g. https://github.com/leapmotion/LeapUn...ses/tag/v3.3.1 and extracting LeapMotion-v3.3.1-UE4.22.7z Plugins folder into your project root.

    That would depend on Leap Motion supporting the device. Best bet to track LM news would be https://www.leapmotion.com/news/

    Code:
    ProducerLambdaFuture.Reset();
    The error was:-
    Code:
    class "TFuture<void>" has no member "Reset"
    Apparently UE4 4.19 doesn't have the member function Reset (maybe less advanced lol) so I just commented it. Is it okay?
    Should be ok, but with the caveat that it if you run your app without a leap motion service running it may be left hanging in the taskbar (it shouldn't but there is a risk for that particular case). That particular section is used to forcibly cleanup in the case of the leap service doesn't respond to polling (which is a v4 leap service bug we're working around).

    Hi all - this might have been obvious to some, but certainly wasn't for me. When downloading any .7z module or plugin from GitHub, it is essential that you unzip the download with 7-zip: https://www.7-zip.org/ in order for everything to extract cleanly. Using WinZip, ALZip or other alternatives won't work properly.

    I followed all your steps but I still get this when moving my right hand.

    I think I see the problem. Currently it's setup to have a standard tracking where left = left etc, but you want a mirror mode where you right hand is the character's left hand facing you. In your particular example, if you rotated your characters 180 degrees they would line up with your tracked hands.

    To do a mirror mode, you'd need to reflect the tracking data about a Z plane (math: http://mathworld.wolfram.com/Reflection.html but you can likely do vector subtraction from a fixed point for simpler math). There's nothing built in that supports it in e.g. bodystate, instead I'd recommend starting with tracking data from a leap component, reflecting that data and feeding it into a mesh. See the direct rigging examples on how to use the leap component based setup https://github.com/leapmotion/LeapUn...igging/LowPoly

    Thx for your time.
    repo uses git lfs, if you do not use git lfs, download a release (.7z) at https://github.com/leapmotion/LeapUn...ses/tag/v0.3.7. If you clone without lfs you may end up with an empty directory.
