[Plugin] Leap Motion - Event Driven

Hi, I have just a couple of questions. I’m working with a group for a VR project at our college and we bought the Leap Motion hoping to use it as an in between while we waited for our VR gloves to come in (hopefully some time next month or April) I found your plugin and have been trying to adapt it into our project(which is very basic at the moment) I’m able to get everything to work correctly when I first load the plug in into the project. Play in Editor works great, the leap recognizes both hands all individual finger movements etc.

FIRST ISSUE:
However when I try and launch standalone, after the whole cooking process I get an error telling me that Leap.DLL could not be found on my computer. I’ve checked through the files in the project and the files that came with your plugin as well as Leaps SDK. Leap.dll is all over the place, I even copy pasted it to several other locations, still getting this error every time I try and launch stand alone.

Launching is not supported, use play or play standalone. If you want to distribute it, the packaging/shipping instructions found on the readme.

SECOND ISSUE:
After initially loading the Leap plugin into our project and everything working great, I saved everything so as not to lose the setup, as it was working and then closed UE4. When I went to launch the project again later, I get around 430-450 load errors on launch, varying each time I launch the project. I didn’t change anything between getting leap to work and closing the project and didn’t touch the project between closing it and relaunching it later that same hour.

Attached are a couple of screen shots. One showing the content browser from UE4 which shows all of the Leap plugin folders still in the same location I placed them when I got the plugin to work the first time. The other screen shot is just a small number of the Load errors I’m getting when launching after initially getting leap to work.

Side note…I can delete the copy of the project I made to test the plugin with (and in the process deleting all of the leap motion items) then create another copy, re-add all of the leap stuff to it and it works again but only in Play in Editor, and only that first time. After I save/close/relaunch it load errors again. And the Standalone has never worked.

We are using the latest Leap SDK, with UE 4.6.1

the second issue may be related to this: [Plugin] Leap Motion - Event Driven - C++ - Epic Developer Community Forums
TL;DR: If you’re sourcing your classes from C++ you may need to create a middle-man blueprint where you add your leap parts. Still unsure why this happens.
