Drawing UI shapes in a procedural manner is more efficient than using textures.

The MathShapes2D project has 33 primitive shapes which may be combined into more complex shapes and used as masks/gui elements

Procedurally draw your progress bars, circles, buttons, aiming reticules, screen transitions and other elements

The project uses the MPC method to animate these shapes. The Material Parameter Collection is the newer and easier way animate materials.

Some popular shapes provided are Cross, Rounded Rectangle, Horse Shoe, Octagon, Parallelogram and Pie
