Sprite atlas

Imagine you have a game in Unity where you use thousands of materials all across the project, whether for sprite atlas, NPCs, environments, UI, or anything else. In such cases, generating a lot of textures or meshes — or applying materials with multiple shaders — might increase something called "Draw Calls" in your game, sprite atlas.

The original version 1 of the Sprite A 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 system packs textures from sprites, sprites within textures, and sprites in folders into an Atlas Texture. It packs these textures when it enters Play mode, or when it builds the Player or an AssetBundle. Note: From Unity Also referred to as a texture atlas, image sprite, sprite sheet or packed texture.

Implemented in: UnityEngine. Thank you for helping us improve the quality of Unity Documentation. Although we cannot accept all submissions, we do read each suggested change from our users and will make updates where applicable. For some reason your suggested change could not be submitted. And thank you for taking the time to help us improve the quality of Unity Documentation. Sprite Atlas is an asset created within Unity. It is part of the built-in sprite packing solution. A Sprite Atlas stores a list of packable assets. Sprite or Folder. Before the packing process begins, these packable assets will be grouped and traversed to gather all the sprites from them. These will be used in the packing process. It also provides dedicated texture settings in the inspector for the packed texture. The original texture settings of the sprite will have no effect on the packed texture. By default, Sprite Atlas will be referenced by the sprite and be available at runtime.

This is a buffer to prevent pixel The smallest unit in a computer image. A texture atlas for a video game.

In computer graphics , a texture atlas also called a spritesheet or an image sprite in 2d game development is an image containing multiple smaller images, usually packed together to reduce overall dimensions. In an application where many small textures are used frequently, it is often more efficient to store the textures in a texture atlas which is treated as a single unit by the graphics hardware. Careful alignment may be needed to avoid bleeding between sub textures when used with mipmapping and texture compression. In web development , images are packed into a sprite sheet to reduce the number of image resources that need to be fetched in order to display a page. Contents move to sidebar hide. Article Talk.

A 2D project uses sprites A 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 and other graphics to create the visuals of its scenes A 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. This means a single project can contain many texture files. Unity typically issues a draw call for each texture in the scene; however, in a project with many textures, multiple draw calls become resource-intensive and can negatively impact the performance of your project. A Sprite Atlas A texture that is composed of several smaller textures.

If you enable this property, Unity creates a copy of the Texture data. You can use either of these batching techniques depending on your project. Suggest a change. Version: You can see in the screenshot above that the draw call batches have been reduced significantly from 12 batches to 2 batches after using the sprite atlas for our images. There are two types of draw call batching. In other projects. In computer graphics , a texture atlas also called a spritesheet or an image sprite in 2d game development is an image containing multiple smaller images, usually packed together to reduce overall dimensions. Sprite sheet for the video game Blades of Exile. Sets the resolution, the file size with associated memory size requirements, the pixel dimensions, and the quality of your Textures for each target platform of the Sprite Atlas. A Sprite Atlas stores a list of packable assets. Scripting API.

Follow the steps below to create a Sprite A 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 asset and how to select different options and features when you include a sprite atlas in your projects.

Think of each unique Scene file as a unique level. Unity Manual. Wikimedia Commons. Before the packing process begins, these packable assets will be grouped and traversed to gather all the sprites from them. The original version 1 of the Sprite A 2D graphic objects. Static Batching : This batching combines static GameObjects and renders them together. Retrieved 16 October Dynamic Batching : For small enough meshes, this batching technique transforms their vertices on the CPU, groups similar vertices together, and renders them in one draw call. Hidden categories: Articles with short description Short description matches Wikidata. A Draw Call is a call to the graphics API to draw an object — like a mesh — and draw call batches are the calls done to the graphics API in bulk to draw objects together.
