Support for Paper2D sprites in UMG was added in 4.13 which is great but there’s no easy way of dynamically changing which sprite an Image uses.
Images currently have SetBrushFromTexture, SetBrushFromMaterial, and SetBrushFromAsset functions but are missing a SetBrushFromSprite function. I’ve gotten around this by making a SlateBrush for each sprite I want to use in UMG but it would be nice if I didn’t have to do that.
