[lcjefferson]

I'm trying to open in version 4.26 of unreal, however, there is an error. Did they have an updated version of the plugin?

Hey sorry guys for my late reply and posting how to rebuild and compile the Plugin, I was busy and caught up with some projects,

Straight to the point, I will be explaining step by step with pictures for ease of understanding, How to Rebuild Leap Motion Plugin in Unreal Engine 4.25 or 4.26 successfully.

1- First you need to go to the link and download Microsoft Visual Studio 2019 , then make sure you download the community version as it is free, upon installation, you will prompt to tick what kind of installation components you want to install, and follow the picture which is idle for Unreal Engine.

2- Second, after installation, download the latest Leap Motion Plugin, in your project folder, create a folder calls "Plugins" and then extract the LeapUnreal-3.6.0.zip file into the "Plugins" folder.

3- After extractions, click on the project file to open, then you will prompt with the rebuilding the plugin, click on Yes to begin the rebuilding process.

4- You need to wait for the rebuild process, you do need to do anything, just sit back, you can click on Show Log to see the rebuilding process if you like to, it might take a while depends on your system.

5- Once the rebuild process is done, the project automatically will be opened as the picture below

6- BINGO! Unreal Engine has rebuilt the plugin successfully, as you tick show plugin content, you can find Leap Motion Content folder in under you plugin content.

7- I suggest to close Unreal and connect your leap motion and then reopen your project and you are ready to configure and use your beautiful leap motion controller, you can check the "How to use it - Convenience Rigged Pawn" following the link at

PS: If you have a VR setup alongside your Leap Motion Controller, you can start with Option 1. VR Mode- Example Pawn and test your Leap Motion Controller and VR set in VR Mode, if you do not have VR set, you can still use Option 2. Desktop Mode - Example Actor to begin to use your Leap Motion Controller without using VR mode in Normal Play Mode or Simulation Mode.

You can check out the test video of Realtime Leap Motion Controller in Unreal Engine.

Hope this could help you to kickstart your amazing journey with Leap Motion Controller and Unreal Engine.

Cheers 👍

Regards.
Omid.

Thanks @omidghajar for your input and helping others. We haven't got an official 4.26 release done yet, but the current master contents should be compatible with 4.26 and contains a few other fixes. As it's not part of an official release (i.e. not recommended for production) it hasn't been through an official QA test process but might be a good starting point for people.

Thanks for this guide.
I've followed all steps with Visual Studio Community 2019, but still, LeapMotion returns an error while compiling in Unreal 4.26.1, with this error: LeapMotion could not be compied. try rebuilding from source manually.
After starting the project it prompts for rebuilding the plugin, then it starts building
It returns the following error:
LeapImage (83): error C2027: use of undefined type 'FTexture2DResource'

[getnamo]

Replace FTexture2DResource with FTextureResource for 4.26 compatibility fix

Replace FTexture2DResource with FTextureResource for 4.26 compatibility fix

I got another issue after replacement.

'GetCurrentFirstMip': is not a member of 'FTextureResource'

I still get a "fatal error" message when building the .exe of the game in the Shinpping configuration in UE4.26 Does anyone have this problem?

As @MaxPalmer-UH said and I quote "not recommended for production) it hasn't been through an official QA test process" so it is advisable not to use it yet for shipping the product, but maybe he would be able to guide you for this issue.
