How to Convert Unreal Engine 5.1 Blueprint Project to C++ Project

To begin, open your project in the Unreal Engine 5 or a newer version of the editor. 

Next, access the New C++ Class Dialog by selecting Tools and then New C++ Class. 

From there, create a new "None" class and press "Create Class." 

You might receive a warning message regarding the game module compilation, but you can disregard it and choose "No." 

After closing any pop-ups, warnings, or success notifications, exit the Editor. 

Proceed to your project's folder, right-click on the .uproject file, and select "Generate Visual Studio project files." 

Double-click your project's .sln file to open it in Visual Studio. 

In Visual Studio's Solution Explorer, find and choose your project. 

Select "Development Editor" in the build configuration drop-down menu. 

Right-click on your project and select "Build" to compile it without any errors. 

Afterward, set the build configuration drop-down menu to "Development" and right-click on your project to select "Build" again. This build may take several minutes, but once it is complete, your project should be compiled without errors.
