Yes , there are files in those folders, as you can see in one of the screenshots posted by asmithey. Gamedate time can be directly set in the detail customization panel , and system date time can be used by checking “Use system datetime” checkbox. You can disable the userinput widgets and the in game widgets by unplugging the respective comments “User Input Widgets” , and “Creating Widgets” from the main blueprint. You can also put the time in your userinput widget in runtime like you said, but since you are unplugging it anyway , you won’t be needing that.
If you still face issues , once I reach home I will explain you with screenshots. Also I will soon update this. Let me know if you need additional features or anything that is currently not very convenient.
Can you please re download , to check if the files are there in those folders ?
