The Tilemap Renderer component renders the TilemapA GameObject that allows you to quickly create 2D levels using tiles and a grid overlay. More info
See in Glossary in the SceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary. Unity creates Tilemaps with the Tilemap Renderer attached by default. The Tilemap Renderer can:
The Render Mode affects the sorting of Tilemap 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 when rendered.
Chunk Mode is the default rendering mode of the Tilemap Renderer:
When set to Chunk Mode, the Tilemap Renderer handles Sprites on a Tilemap in batches and renders them together. They’re treated as a single sort item when sorted in the 2D Transparent Queue. While this reduces draw calls, other renderers can’t render between any part of the Tilemap, preventing other rendered Sprites from interweaving with Tilemap Sprites.
In Chunk Mode, the Tilemap Renderer isn’t able to sort Tiles from multiple textures individually and doesn’t render the tile sprites consistently (refer to the example below).
Pack all the individual Sprites that make up the Tilemap into a single Sprite Atlas to solve this issue. To do this:
Create a Sprite AtlasA texture that is composed of several smaller textures. Also referred to as a texture atlas, image sprite, sprite sheet or packed texture. More info
See in Glossary from the Assets menu (go to: Atlas > Create > Sprite Atlas).
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.
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.
In Individual Mode, the Tilemap Renderer sorts and renders the Sprites on a Tilemap with consideration of other Renderers in the Scene, such as the Sprite RenderersA component that lets you display images as Sprites for use in both 2D and 3D scenes. More info
See in Glossary and Mesh RenderersA mesh component that takes the geometry from the Mesh Filter and renders it at the position defined by the object’s Transform component. More info
See in Glossary. Use this mode if other Renderers interact with Sprites and objects on the Tilemap.
In this mode, the Tilemap Renderer sorts sprites based on their position on the Tilemap and the sorting properties set in the Tilemap Renderer. For example, this allows a character sprite to go in-between obstacle sprites (refer to the example below).
Using the same example in Chunk Mode, character sprites might get hidden behind ground sprites:
Using Individual Mode might reduce performance as there is more overhead when rendering each sprite individually on the Tilemap.
To sort and render tile sprites on an Isometric Z as Y Tilemap, set the Transparency Sort Axis to a Custom Axis. To do this:
Refer to the page on Creating an Isometric Tilemap for more information about the Transparency Sort Axis settings.
