C++ project from 4.15 to 4.18 doesnt work

Hi, I’m trying to drag and drop a project from 4.15 to 4.18 in c++. I was able to generate c++ files, but the module is not rebuild.

The Creator of the project answered me with this, but did not help any more: Hello, with a recent unreal update they changed the source now all C++ structs that are exposed as properties have to be of “BlueprintType”. You can add the BlueprintType keyword to the given structs in the source files yourself if you want, otherwise you have to use an older engine version or wait for an update.

Looks like you are trying to upgrade a project that was originally based on a template, issues like that are expected.

Fortunately, you have just a couple of fixes to do. Open your project in Visual Studio (or any other editor), and fix the problems.

You make quite a big jump, the engine source code is constantly changing.
