Unity has introduced several new 2D features including improved sprite atlas APIs, experimental APIs for the sprite editor window, and revolutionary 2D world-building tools with improvements to tilemaps that now support hexagonal and isometric tiles. Additional new features include sprite shape tools that allow sprites to tile along custom shapes, 2D animation phase 2 with efficient character creation workflows, sprite rigging in the sprite editor, pixel perfect rendering, and 2D lights and shadows. Users are encouraged to provide feedback on preview features.

13. Graphics

14. Motion and changes in resolution cause imperfections in pixel-art
rendering.
Solution?
Users would have to write their own script to remap definition of pixels.
Better solution?
2D Pixel Perfect Package.
Pixel Perfect
