Deformed hand after packaging Unreal Engine project

[b_lightyear]

Hi,

I'm creating an application that uses Leap Motion mounted on a Vive. I created an empty project in Unreal Engine and installed the plugin as described on https://github.com/leapmotion/LeapUnreal . The application uses the LeapHandsPawn actor.

When running the application from the editor, the application seems to work. The hands are tracked correctly and look ok. However, when the application is packaged, the hands are deformed. The fingers look ok for the most part, but especially the palm of the hand looks like it has no volume, like it's flattened. This mostly seems the case on the ventral/palmar side of the hand. Watch the included pictures to see what I mean.

I used version 4.20.1 of Unreal Engine to create the video. If you have any question about my setup, feel free to ask. I'm aiming to build a multiplayer application where everyone can track his hands with Leap Motion and where players can see each others hands.

Does anyone know what the problem could be?

It appears a recent update broke something for rigging but only in packaged builds.

I've managed to replicate the problem and I opened an issue on the plugin for it here: https://github.com/leapmotion/LeapUnreal/issues/14. The issue will get updated as it gets addressed there.

Thanks for spotting this!

This is CAPITAL, it´s impossible to release anything in 4.20 with this bug, and there is no workaround, and it´s impossible to recreate a full project created in 4.20 in 4.19 without dedicating A LOT of time, meaning practically 1 month.

Please we need a solution for this ASAP, it´s been more than a month with this super bug, and it´s a full showstopper

Thanks.

Thanks for resolving this Alex!!
I have downloaded your files.
How do I update Leap Motion using your update files. I am on Windows 10, Using UE 4.20.1
Sorry for the simple question.

What I did; after I've downloaded the files. I replaced the 'Plugin' folder inside the root of my Unreal Project, it worked just fine

You should be able to download the release and swap it out for the existing LeapUnreal plugin using the setup process described at https://github.com/leapmotion/LeapUnreal

That is the correct way, delete the old leap motion plugin and drag and drop the new one. Dragging over and hitting override usually works, but it won't delete files if they were removed between versions.
