Sort isometric Sprites with the Sprite Atlas

In Chunk Mode, the TilemapA GameObject that allows you to quickly create 2D levels using tiles and a grid overlay. More info
See in Glossary Renderer isn’t able to sort Tiles from multiple textures individually and doesn’t render the tile spritesA 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 consistently.

Pack all the individual Sprites that make up the Tilemap into a single Sprite AtlasA utility that packs several sprite textures tightly together within a single texture known as an atlas. More info
See in Glossary to solve this issue. To do this:

1. Create a Sprite Atlas from the Assets menu (go to: Atlas > Create > Sprite Atlas).

2. Add the Sprites to the Sprite Atlas by dragging them to the Objects for Packing list in the Atlas’ InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
   See in Glossary window.

   

3. Click Pack Preview. Unity packs the Sprites into the Sprite Atlas during Play mode, and correctly sorts and renders them. This is only visible in the Editor during Play mode.
