A Variant Sprite Atlas is a type of SpriteA 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info
See in Glossary Atlas that does not contain its own list of selected Textures as it has no Objects for Packing list in its properties. Instead, it receives a copy of the content from the Sprite AtlasA utility that packs several sprite textures tightly together within a single texture known as an atlas. More info
See in Glossary set as its Master Atlas.
Variant Sprite Atlases are an optional step in the Sprite Atlas Workflow. Their main purpose is to create a variation of another Sprite Atlas’ Textures but with a different scaled resolution.
