I am attempting to set some post process settings via a button in a widget bp. However, I cannot seem to figure out how to communicate with a post-processing actor in the scene… nor a post-processing component (preferable approach) in another actor bp. I have not been able to find any information on this specific topic. Any advice?
HI!
You need use Event Dispatcher for create communication between UMG and other blueprints.

For a quick example, I used the Level Blueprint. Don’t forget to create a variable that will contain the current widget. Without it you will not be able to create a link between the UMG and other blueprints.
This is result:
