[UMG] Slider handle not visible at start

Look where it says “value” in your slider settings. Sliders are a 0-1 scale. If you’re loading a value that is your FOV. e.g. 90 or whatever, it may be moving the bar off the scale until you click and change value. I’d recommend deciding on a max and min fov so you can get a % on a 0-1 scale that you set your slider value to instead.

You are right! I forgot to map the FOV value with the MapRangeClamped node in the LoadGameSettings function!

Problem solved, thank!

Problem solved, i forgot to map FOV value to 0-1 range, used a MapRangeClamped node.
