Default Texture settings

The Aseprite Importer sets the following default settings to the generated texture:

The Aseprite Importer is available after you import a .ase/.aseprite file into your Project.

Aseprite Importer Inspector properties

Property	Description
Import Mode	How the file should be imported. This is set to Animated Sprite by default.
	Sprite Sheet	The file is imported as a Sprite Sheet, and can be sliced up in the Sprite Editor.
	Animated Sprite	The file is imported with animation in mind. Animation assets are generated and attached to a model prefab on import.
Pixels Per Unit	Sets the number of pixels that equals one Unity unit.
Mesh Type	Sets the Mesh type that Unity generates for the Sprite. This is set to Tight by default.
	Full Rect	Unity maps the Sprite onto a rectangular Mesh.
	Tight	Unity generates a Mesh based on the outline of the Sprite. If the Sprite is smaller than 32 x 32 pixels, Unity always maps it onto a Full Rect quad Mesh, even if you select Tight.
Generate Physics Shape	Generates a default physics shape from the outline of the Sprite/s when a physics shape has not been set in the Sprite Editor.

Property	Description
Include Hidden Layers	Enable this property to include the hidden layers of the .ase/.asperite file in the import. This property is set to False by default.
Import Mode	Use this property to specify how the layers from the source file are imported. This property is set to Merge Frame by default.
	Individual Layers	Every layer per frame generates a Sprite.
	Merge Frame	This is the default option. All layers per frame are merged into one Sprite.
Pivot Space	Select the space pivots should be calculated in. This property is set to Canvas by default.
	Canvas	Calculate the pivot based on where the Sprite is positioned on the source asset's canvas. This is useful if the Sprite is being swapped out in an animation.
	Local	This is the normal pivot space used when importing a standard image in Unity.
Pivot Alignment	How a Sprite's graphic rectangle is aligned with its pivot point. This property is set Bottom by default.
Mosaic Padding	External padding between each SpriteRect. This property is set 4 pixels by default.
Sprite Padding	Internal padding within each SpriteRect. This property is set 0 pixels by default.

Property	Description
Model Prefab	Enable this property to generate a model prefab setup to look like the first frame in Aseprite. This property is set to True by default.
Sorting Group	Add a Sorting Group component to the root of the generated model prefab if it has more than one Sprite Renderer. This property is set to True by default.
Shadow Casters	Enable this property to add Shadow Casters to all GameObjects with a SpriteRenderer. This property is set to False by default. Note that this checkbox is only available in Unity 2023.1 and newer.
Animation Clips	Enable this property to generate Animation Clips based on the frame data in the file. Every tag in Aseprite generates one Animation Clip. If no tag is present, one Animation Clip is generated which covers all frames in the file. The Animation speed is based on the Constant Frame Rate defined in Aseprite. The length is based on the number of frames included in the tag/file. This property is set to True by default.
Export Animation Assets	The Animator Controller and the Animation Clips are generated as Read Only assets. This option can be used to export editable versions of these assets.

The Aseprite Importer Preferences can be found at Unity > Settings > 2D > Aseprite Importer.
