Hands crushed in release but ok in editor

[juangea]

HI there.

I have a big problem, I was just about to release the app for my client and when I did the packaging for my client and tested it the skin of the hands was completely broken, the actions were functioning correctly, but the mesh whas broken, like crushed with mixed skin weights or something similar.

Broken in package:

Hand in editor:

Any idea on how to solve it? I need to release this ASAP

There appears to have been an engine api change or bug in 4.20. Current fix: downgrade to 4.19 until source is located

I can´t downgrade the full project to 4.19!

It´s completely impossible...I´ll try, but I think I won´t be able, it´s a big project with LOTS of things

Second potential option: use direct rigging via LeapLowPolyHand instead of BSLowPolyHand. It is likely that this rigging setup doesn't have the same problem.

Thanks for that option, I´ll try it, i´m also trying the downgrade path just in case, but the leap plugin refuses to load, should I have to download a previous plugin version?

Thanks

I´m trying to change the animation blueprint from BSLowPolyRightAnimBP to LeapLowPolyRightAnimBP but it´s not working at all, the hand is not showing up

Hi Getrnamo.

I tried to roll back to 4.19, but it destroys all my maps and assets and refuse to open them telling me that they were created/saved with a newer engine version, I will have to fix it in 4.20, can you give me a hint on how can I replace the hands with the direct rigging ones?

I´m usijng the hands of the UI interaction module

And now something weird happened, my right hand is totally broken, even when I have the BS animation blueprint applied and compairing left to right, everything is the same configuration : P

Please help me, it feels like the project is falling apart : P

You can pretty easily delete the plugin and grab a new download in case your assets have changed, optionally make sure you have a backup before doing drastic changes like engine downgrades.

I just checked the lowpoly direct rigging in packaged mode and it appears to have the same issue unfortunately. This is surprising and may help narrow the reason for the bug. It's some behavior only happening in packaged mode which is adding some HMD based rotation early in the data chain. Working through it atm will ping an update if I find something.

Yes please, the app should go live 12 october in a big event, the downgrade is completely impossible, I need to be able to compile and package it : S

[juangea]

BTW I solved the problem with the right hand, I´m unsure what happened, but I restores a previous version of the files form my SVN repository and everything went back to normal.

Anyways, this is a BIG problem, I hope you can fix it soon please :P

[juangea]

BTW is it working with other hands in the demos? Like the high resolution ones or the character hands?

fixed in https://github.com/leapmotion/LeapUnreal/releases/tag/v3.0.1
