I am new to UE4 and I am making a small game to acquire some experience.
I would like to make the screen appear red for 0.5 seconds when the character is hit/damaged.
I found out how to make fade in and out with matinee, but I can’t change the color and I’m not sure if it would be the right way to do it.
In your HUD script, set up a timeline (more efficient than a matinee for this) and use this to drive the color change through post process volumes. Specifically look for the vignette. See if that helps get you what you are looking for.
This is super easy to do in Blueprints in 4.6 Even though this was marked as RESOLVED, I wanted to add this for all of us who are trying to figure out how to do this now, since this is the thread that pops up most frequently on Google when you search on how to do this.
