Hi all
I m absolutely not a developper, but I need really this plug.
I tried to follow the explication video, but…
First, I download Code soruce of UE4, and I unzip all in a folder. I tried to click on GenerateProjectFile, without success : I ve an error message.
I tried to copy/past this content in different folder ( in my project folder, in UE4 Engine folder…) same result
After fews test I found a solution for rebuilt with other way ( generated Visual Studio File, and rebuild project in VS )
I can open my project, with the camera stereo, Left Eyes texture, Right eye etc… like a tutorial video.
But i don’t understand how to launch BenchmarkStereo for to generate the panoramic render…
Somebody can explain at a noob ? 
thanks all !
