Description

The tessellation detail to be used for generating the mesh for the associated sprite if the SpriteMode is set to Single. For Multiple sprites, use the SpriteEditor to specify the value per sprite. Valid values are in the range [0-1], with higher values generating a tighter mesh. A default of -1 will allow Unity to determine the value automatically.
