how would I go about doing a mouse over glow for certain items?

Im wanting to make it so certain items that you can “collect” glow when you mouse over them but at the moment i’m not having any luck what so ever… I feel like im missing something basic.

Here is a really good guide on an outline effect.

From there, you’ll want to enable mouse-over events in your player controller (or -provided you want to move the crosshair over items to interact- set up a line trace from the player’s camera to simulate mouse overs) and then override ‘on begin cursor over’ and ‘on end cursor over’ in the actor. Toggle the outline from there.
