When do UMG binds update?

Simple example, I have a variable on my character called XYZ. On construct I cast to that character and set a reference to it. Then I bind a text field to getCharacterReference -> Get XYZ -> Convert to Text -> Return Text.

Will this update every frame or only when the value changes?

I have a button that binds its image based on an array and a foEach loop and I would hate for 20 of these buttons to be running lengthy forEach loops every frame. Currently I have those images being set on construct rather than using the Bind system in UMG, but it seems like a Bind would be less of a hassle for me. Thoughts?

UMG binds update per tick unfortunately… I personally almost never use them unless I actually know the value changes every frame.

Construct event is the way to go.
