actually no shader! with godot, you can go into project settings -> window (i think?) and then set the scale up. a couple other tweaks to make it work but then flat colors make it look nice as well
yeah give it a shot! If you’re curious I can go get the actual setting name in a bit and write up some steps! I tried a ton of different methods but this one is easy and works real good. Makes 3D modeling easier too because the imperfections don’t really show up
