In SM63R, water is essentialy an animated polygon with a surface "shader" which calculates interactive waves. The last part can lead to some issues and problems, if the polygon is created incorrectly.
- At least 4 or more points
- The surface must be completely horizontal. If not, the water is completely static and touching the surface crashes the game.
- The angle of both vertices should be 90º. If not, it flickers
