Image import settings

After you have imported an image to your project, for the most intuitive results, it’s recommended that you apply certain import settings for Textures, Sprites, and Vector images before you use them as a background for a visual element in the UI Builder.

纹理

The recommended import settings for a Texture image that you use as a background for a visual element:

属性：		值：
Texture Type		Default
	Non-Power of 2	无
	Compression	无
	Alpha Is Transparency	true
Texture Type		Editor GUI and Legacy GUI
	Non-Power of 2	无
	Compression	无
	Alpha Is Transparency	true
Texture Type		Sprite (2D and UI)
	Compression	无
	Alpha Is Transparency	true
	Sprite Mode	Single
	Mesh Type	Tight

Sprites

The recommended import settings for a Sprite image that you use as a background for a visual element:

属性：		值：
Texture Type		Sprite (2D and UI)
	Compression	无
	Alpha Is Transparency	true
	Sprite Mode	Multiple if file contains multiple sprites, Single otherwise
	Mesh Type	Tight

Vector images

The recommended import settings for a SVG Vector image that you use as a background for a visual element:

属性：	值：
Generated Asset Type	UI Toolkit Vector Image
Tessellation Settings	Basic
Target Resolution	Lowest value that produces satisfactory results

Tip:

You can apply default presets to Assets by folder to automatically set your desired import settings.
All image types are subject to dynamic atlasing if they’re not already in an atlas. (An image is in an atlas if imported as a Sprite with Sprite Mode set to Multiple, or if you have manually added it to a Sprite Atlas asset.) You can configure dynamic atlasing in a Panel Settings asset.
