How can I edit Post Process Blendables on Mouse over?

I’m trying to highlight a static mesh when the mouse cursor is hovering over it (Same effect used in L4D for picking up ammo, guns etc), but I cant seem to change the post process volumes settings via BP. Here’s an example of the blueprint I’m using so far:

I’ve also tried variations from all of the following links/questions and none of them have worked yet:

Is it possible to highlight an object on mouse over in UE4 yet? If so, how can I have it highlight the object on mouse over, then remove the highlight once the mouse cursor is no longer hovering over the static mesh?

Thanks in advanced!

(4.10.1)

I could not find find any information about it also and I needed it badly for interactive objects in Top Down point-and-click game. I finally did it like this. If there is any other more efficient or flexible in further work way please let me know :slight_smile:

Be sure you have “Enable Mouse Over Events” checked in your Controller Blueprint

You need material. You can get one from Content Example. It’s called “M_Highlight”


I had ERROR in node you can see in screenshot. Just select this node and change it Scene Texture Id from Scene Color to PostProcessInput() and Save. I also changed it color to be more “juicy”

  1. Find in your scene Outliner Post Process Volume. If you dont have one, make one :slight_smile: and add in Settings → Blendables the material you just “made” :slight_smile:

  2. Then I simply added this nodes to object blueprint (one i need to be outlined/interactive on mose over)

Variable “Highlight” in Variables on last screen is not important. You dont need to create it, I just removed it (trash from earlier attempt :slight_smile: )
