Sprite atlas

In computer graphicsa texture atlas also called a spritesheet or an image sprite in 2d game development is an image containing multiple smaller images, sprite atlas, 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 sprite atlas 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 developmentimages are packed into a sprite sheet to reduce the number of image resources that need to be fetched in order to display a page, sprite atlas.

Imagine you have a game in Unity where you use thousands of materials all across the project, whether for characters, 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. 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. Having too many batches of draw calls in your game might slow down your game. Even worse, it might significantly affect your FPS and make your game unplayable if it isn't managed well.

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. There are no changes to the Inspector A 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 properties and settings from that of Sprite Atlas V1 except for the following. The imported Sprite Atlas object is located at the bottom of the Inspector. The Pack Preview window displayed at the bottom of the Inspector window. Sprite Atlas V2 is automatically enabled by default by the Editor from Unity If you select Sprite Atlas V2 - Enabled for Builds , Unity only packs Sprite Atlases when building Players, AssetBundles, or Addressable build scripts A piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info See in Glossary. When the Editor is in Edit mode, sprites continue to use their original textures and not textures from a packed Sprite Atlas. Version:

Sprite Atlas is an asset created within Unity.

Unity creates the Sprite Atlas in the Assets folder, with the file extension. Version: Language : English. Unity Manual. Unity User Manual

Sprite Atlas is created via the menu option in the Editor and will stay as an asset Any media or data that can be used in your game or Project. An asset may come from a file created outside of Unity, such as a 3D model, an audio file or an image. Sprite Atlas asset provides a set of texture settings for the packed texture. Regardless what was the texture settings 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 being pack in an atlas, the result atlas texture will only respect the settings in the atlas asset. User will be able to create another Sprite Atlas A texture that is composed of several smaller textures. Also referred as a texture atlas, image sprite, sprite sheet or packed texture.

You are strongly recommended to use Destroy instead. Sprite Atlas. So, to solve these issues, we will have to use an optimization technique called Draw Call Batching. This panel lets you override these settings on the individual Textures that the Sprite Atlas contains. Careful alignment may be needed to avoid bleeding between sub textures when used with mipmapping and texture compression. Variants will not repack a new texture from the packable list. 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. To have a basic idea of what draw calls do, I have created a simple Unity scene with multiple UI images around them. Version: Contents move to sidebar hide.

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.

GetSprite Clone the first Sprite in this atlas that matches the name packed in this atlas and return it. This maximizes the density of Sprites in the combined Texture, and is enabled by default. Sprite Atlas. Version: You are strongly recommended to use Destroy instead. Language : English. It also provides dedicated texture settings in the inspector for the packed texture. Sprite Atlas V2 is automatically enabled by default by the Editor from Unity ToString Returns the name of the object. So, in this blog, we will be optimizing draw calls of a simple UI that uses multiple images and materials using a sprite atlas. Unity packs all items in this list into the currently selected Sprite Atlas. So, to solve these issues, we will have to use an optimization technique called Draw Call Batching.
