That’s correct @dingtech; as of 4.20, base include paths relative to the “Public” directory of Engine source files have been added to reduce the number of public include paths needed for Engine modules. However, you may use ModuleDirectory and EngineDirectory properties if you’d like to root to a particular directory. As you folks have already figured out, if you’re u[FONT=courier new]sing System.IO; the following syntax can be used where “MyFolder” is the name of the directory under the current module you’d like to include:
[FONT=courier new]PublicIncludePaths.Add(Path.Combine(ModuleDirectory, “MyFolder”));
