I’m trying to compile the Mixer Interactive plugin for UE 4.20, however, I’m now running into an error that seems to be relating to the HostProject that gets made during the compile. If I’m missing anything related to Visual Studio let me know. Adding one thing from VS helped get the process further but now this error happens later. link text
