I was creating a menu for my game and attempted to add text, but it didn’t appear as pixelated as I expected. I did some digging to find answers, but I had no luck with that. Here is the scene along with a screenshot that I will attach; I hope it helps!
If you want pixel fonts without smoothing, disable antialiasing in the font import options and reimport. Also, for the Label, under CanvasItem, set Texture → Filter to Nearest.
