    Again, Thanks for the great plugin!

    I went through the tutorial and everything works with the rigged character. I started to recreate with the floating hands actor but no go. I tried to follow Cantonice's suggestion but I'm missing something. I made a child of the LeapRiggedEchoHandsActor and inside that bp put the 'pickup' and 'closest hand' functions, basically recreating all I did for the rigged character. Although I have collision, my print to screen functions aren't working and I can't pickup anything. Any suggestions?

    Thanks
    Dave

    Hello all,
    I'm new to UE4 and I need to use Leap Motion for a project.

    My question is: Does the Leap Motion plugin work with Mac OS X El Capitan and with UE4.14?

    Thanks in advance!

    The only Item that I copied to the Project is the LeapRiggedEchoHands

    Epic has Identified this as a Bug now.

    https://issues.unrealengine.com/issue/UE-42492

    I did find a work around.

    If you uncheck the "Event Driven Loader Enabled" it will not crash, but it will throw an error about loading DamageTypes.

    I do not need damage in my project, so I disabled damage in my project, restarted the UE4 Editor and it is now running without crashing.

    This is not a final solution, but this allowed me to send out a runnable demo to my client.

    Thanks for getting back to me.

    Unreal UE4 version 4.15 and LEAP Motion Crashing when Running Standalone Game

    When I enable the LEAP Plugin and Add it to a UE4 4.15 Project and Launch it as a Standalone game,
    I get this error.

    I do not get an Error if I run it in Preview Mode. Only when I try to Build the Deployable Game.

    I have tried this on multiple computers.
    I have started with Blank Projects.
    As Soon as I add a Leap Enabled Character, even the Default ones with the Plugin, I can no longer Build a Windows Deployable Standalone using the Launch Button in UE4 4.15

    This works fine in UE4 4.14

    Please help!
    This is Killing my Project right now.

    I have included the screen shot and all errors I can Find.

    Haven't had a chance to try 4.15 yet, your problem appears to be related to https://github.com/EpicGames/UnrealE...ding.cpp#L1915 (epic github access required) which is the first time I've ever seen that line. Try posting on answerhub to get some epic response on this as there is currently no documentation on this.

    Potential question: do you have both a project leap plugin as well as the engine plugin or only the engine plugin?

    SOLVED
    I was having issues with getting the floating hands to work so I cut and pasted everything to the rigged character. I didn't have the interface in the inherited list for that character. Now that the rigged character works, I'd like to get it functioning on the floating hands.

    Great plugin. In your Jenga tutorial part 2 at around the 10 minute mark you seem to have trouble getting the Pickup interface show up as an event. What did you do to finally make it work. I've compiled like shown but I still don't see the event listed.

    Thanks,

    Dave

    haven't tried 4.13. will do that soon.

    and yes, I did do the offset. still no hands. but i did at one point might have seen my hands at the origin in worldspace, but wasn't sure if that was 4.14 or just something weird i did in 4.12 (at that point i just deleted the project and started over).

    I switched Default Pawn Class to LeapFloatingHandsClass
    Launch VR Preview.
    Vive works fine, but I don't see any hands in front of me.

    I just can't get the hands showing up. Spent two days but no success...

    Mounted in front of the vive HMD
    I created a new Unreal 14.3 engine project.
    I enabled the Leap plugin
    I restarted Unreal
    I created a NewGameMode
    I overrided the game mode with NewGameMode
    I switched Default Pawn Class to LeapFloatingHandsClass
    Launch VR Preview.
    Vive works fine, but I don't see any hands in front of me.

    I just can't get the hands showing up. Spent two days but no success...

    is there a way to get hold of the thumbs up gesture?

    For a chocoloade museum we are making a chocolade creation experience - based on the idea of the leap motion blocks demo.
    It will be very cool, with 3 VR seats and loads of cookies flying around.

    Thank you, Michael

    By the way, thank you for providing the awesome socketio-client-ue4: we use it for bluetooth access of a femto.io Arduino to UE4.
    Glad the plugins are being useful

    You can determine a thumbs up state by getting the xvector from your thumb rotation and taking the dot product between it and the Z up vector (0,0,1). If it's positive the thumb is pointing up. You can also use the dot product to get the angle between the two vectors which can allow you to only recognize a thumb up if its e.g. within ~ 30degrees from the vertical. Finally i'd also check if all your other fingers are close enough to a point near the palm to count making a fist (optionally use the grab event). Using those two criteria you should be able to determine a thumb up gesture (calculate on tick, if criteria is met send a thumbs up event or call your thumbs up function)

    Ps: you should show some chocolate pictures when it's released, i'm sure the hungry devs here would love the see it!

    I' am trying to make grab with Leap Motion for a week now and I can't.

    I tried downloading your Jenga Project and I choose Selected Viewport mode, because I don't have VR and I can't grab anything still with your written Blueprints.

    I tried using older UE4 and Leap motion versions, but I did not succeed. Which versions should I use to set up grab without VR best? because I think in different versions the blueprints are different to, and I am new to them, don't have any idea how to set up if they are different than in the tutorials. I also need that the set up would be in first person.
    Some mechanics have changed, but the grab and release blueprint methods should still work, try to work through the example video and let me know where it stops working for you (e.g. https://www.youtube.com/watch?v=GeLNoqAKoTg) you can also check out this series by Paul Mauviel: https://www.youtube.com/watch?v=fmtB...OUL5fIOkxM8hj8.

    Cheers getnamo, I'm afraid I'm not able to help. But I'm sure hand tracking will gain a lot of interest. So help is on the way..
