Hey I asked a question about including FLEX a while back, and it worked great.

Now I was trying to incorporate your plugin into a 4.15.3 engine build that includes FLEX, Hairworks, Flow, and VolumLight …

I’ve followed your steps … included the relevant folders in the Plugins folder of my Engine && My Project/Plugins folder… when I try to build the project.sln I get the following

You are using the 4.16 source branch with a 4.15 version of the engine (though modified it is still 4.15). Epic changed how module rules are declared in 4.16 so its not directly compatible.

You can download the locked 4.15 branch instead and use that.
