This clock system has a simple blueprint that shows the real time on the Grandfather clock, created in Unreal engine 5.3.2.
Here is a YouTube video preview of this system.
The zip file contains the whole project with a video tutorial of how to migrate the blueprint to your project (Easy).
Note: There is no sound effects included, but I created the nodes necessary to add your sound effects. you would find a comment at where to put your sound effects in the blueprint.
Hope you like it.
