I do a lot of 2d prototyping in last time. But when it comes to simple shapes I use the Polygon2D Node and set ther verticeies manualy. For a rect this is ok but when you want a circle or a hexagon its realy hard. In 3D you can use the meshinstance and the predfined meshes. Yes there is a meshinstance2d but it uses the 3d mesh types so is it using the 3d engine?
So what is the best way to get simple shapes like circle or hexagon for 2D Prototyping?
