Related Questions.This is done using the Asset Database. This dependency information is used to determine the set of Objects that will be included in an AssetBundle. Objects that are explicitly assigned to an AssetBundle will only be built into that AssetBundle.

Any Object that is not explicitly assigned in an AssetBundle will be included in all AssetBundles that contain 1 or more Objects that reference the untagged Object. If two different Objects are assigned to two different AssetBundles, but both have references to a common dependency Object, then that dependency Object will be copied into both AssetBundles.

The duplicated dependency will also be instanced, meaning that the two copies of the dependency Object will be considered different Objects with a different identifiers. This will also cause two different copies of the Object to be loaded into memory if the application loads both of its parents.

Ensure that Objects built into different AssetBundles do not share dependencies. Any Objects which do share dependencies can be placed into the same AssetBundle without duplicating their dependencies.

Segment AssetBundles so that no two AssetBundles that share a dependency will be loaded at the same time. Ensure that all dependency assets are built into their own AssetBundles. This entirely eliminates the risk of duplicated assets, but also introduces complexity. The application must track dependencies between AssetBundles, and ensure that the right AssetBundles are loaded before calling any AssetBundle.

LoadAsset APIs. GetDependencies can be used to locate all of the immediate dependencies of a specific Object or Asset. Note that these dependencies may have their own dependencies. Due to the memory cost of duplicating assets, it is recommended that all projects have such a script. Any automatically-generated sprite atlas will be assigned to the AssetBundle containing the Sprite Objects from which the sprite atlas was generated.

If the sprite Objects are assigned to multiple AssetBundles, then the sprite atlas will not be assigned to an AssetBundle and will be duplicated. If the Sprite Objects are not assigned to an AssetBundle, then the sprite atlas will also not be assigned to an AssetBundle.

To ensure that sprite atlases are not duplicated, check that all sprites tagged into the same sprite atlas are assigned to the same AssetBundle. Automatically-generated sprite atlases will never be assigned to an AssetBundle. Because of this, they will be included in any AssetBundles containing their constituent sprites and also any AssetBundles referencing their constituent sprites.

Sprite atlases generated by external tools will be normal Assets, and can be properly assigned to an AssetBundle. Hard: Assign all Objects that use automatically atlased sprites to the same AssetBundle as the sprites. This will ensure that the generated sprite atlas is not seen as the indirect dependency of any other AssetBundles and will not be duplicated. Due to heavy device fragmentation in the Android ecosystem, it is often necessary to compress textures into several different formats.

Most applications need to ship on older devices where ETC2 support is unavailable.

At runtime, support for the different texture compression formats can be detected using the SystemInfo. This information should be used to select and load the AssetBundle Variant containing textures compressed in a supported format. More information on Android texture compression formats can be found here. The issue described in the following section was fixed in Unity 5. Current versions of Unity are not affected by this issue. In versions prior to Unity 5.

This is not a problem on most platforms. However, iOS limits the number of file handles a process may simultaneously have open to This was a common problem for projects trying to divide their content across many hundreds or thousands of AssetBundles. Is something described here not working as you expect it to? It might be a Known Issue.Unity texture compression is a very important step to developing mobile games for android or iOS. This guide explains how to do unity android texture compression as well as unity iOS texture compression and also explains other texture optimization techniques to improve unity mobile rendering performance!

Textures are generally the main cause of high build filesizes, especially when you have a lot of textures at higher resolutions! Texture compression in Unity allows you to reduce the filesizes of your textures and in most cases makes no visual difference!

Below this line is a list of all assets included into the build ordered by their filesize. From here you can go through the assets and determine what you can do to compress or remove some of these items.

This guide explains how you can compress the images Textures from this list. Unity texture import settings can be adjusted by selecting the texture in the project window to show the texture import settings in the inspector window.

From the texture import settings you can set texture compression, control mip-mapping and adjust few other useful texture settings. Max Size This will set the maximum resolution allowed for this texture, e. Compression This is found in the default tab and seems to be the replacement for auto compression from the older versions of Unity.

I recommend keeping track of your textures and manually setting the unity texture compression where possible.

Format The texture compression format which the texture will be compressed with. Compressor Quality Visible after selecting some compression formats.

Mip maps are smaller versions of the original texture which are used instead of the actual texture when the rendered object is far away from the rendering camera.

They improve GPU rendering performance as the GPU renders much smaller textures and can also reduce texture aliasing without anti-aliasing being needed. Rendering the smaller mip-map textures which are used at a distance is much faster for GPU rendering and reduces harsh aliasing at a distance, especially when used with anisotropic filtering. This example uses strong colour contrasts to make the aliasing effects more obvious but you can see how mipmaps and different filtering levels affect rendering.

Make sure Anisotropic Textures are enabled in your Quality Settings if you want to filter your textures! Remember that not all textures will be equally visible in games, some textures may never even be visible up close! I would also always suggest using texture compression on ALL your textures! There should be a compression method which works for you in all cases without any or very little visual change.

Distribute terrain in zones 3 Answers What are possible causes and solutions to randomly garbled textures on standalone builds?This page details the Texture Overrides Platform-specific settings that allow you to set the resolution, file size with associated memory size requirements, pixel dimensions, and quality of your Textures for each target platform.

More info See in Glossary specific to Android. A description of the general Texture Overrides can be found here. The information contained on this page assumes the reader has working knowledge of DXT and ETC Texture compression A method of storing data that reduces the amount of storage space it requires.

Further information about Texture compression 3D Graphics hardware requires Textures to be compressed in specialised formats which are optimised for fast Texture sampling. This will lead to increased loading times and higher memory usage as Unity must decompress the Textures and store two versions of the Textures used compressed and uncompressed.

This can also have a large impact on rendering The process of drawing graphics to the screen or to a render texture. By default, the main camera in Unity renders its view to the screen. More info See in Glossary performance, especially on older, slower devices. When a user downloads your app, the Google Play Store will automatically install the most relevant APK for their device. Unity can use ETC1 for Textures with Alpha, provided they are placed on an Atlas by specifying the packing tag and the build is for Android.

Under the hood Unity splits the resulting atlas into two Textures, each without alpha and then combine them in the final parts of the render-pipeline. If you absolutely want to store an alpha channel in a Texture, RGBA16 bit is the compression format supported by all hardware vendors.

Version: Language : English. Unity Manual. Unity User Manual Player settings for the Android platform. Gradle for Android. Publication Date: Compressed RGB texture. Pixel size depends on your screen resolution.

Pixel lighting is calculated at every screen pixel. More info See in Glossary 32 KB for a x texture. Compressed RGB Texture. Crunch is a lossy compression format on top of DXT Texture compression.

Crunch produces smaller Textures than by regular DXT1 compression, but with lower quality. Crunch Textures can take a long time to compress, but decompression at runtime is very fast. Compressed RGBA texture. Crunch compression can be used to produce significantly smaller Textures than by regular DXT5 compression, but with lower quality. This is the default Texture format for Android projects in Unity. It does not support alpha. Crunch is a lossy compression format on top of ETC Texture compression.

Compressed RGB Texture with 1-bit punchthrough alpha. Supported by Qualcomm Snapdragon. This compression type uses fixed bit block size, and depending on the pixel block size 4x4 to 12x12it may utilize 8 to 0. The size of the compressed Texture varies from 64 KB for a x Texture 4x4 block, highest quality to 7.

Uses more memory than the compressed formats, but could be more suitable for UI User Interface Allows a user to interact with your application.

For additional information on the texture compression formats, see Texture compression formats for platform-specific overrides. In particular, see the Notes on Android at the end of the topic. Note : Texture Compression is a global setting. Individual textures override the global setting. This option allows you to choose between the uncompressed image quality and the amount of memory the uncompressed texture occupies. Unity supports two Android build systems: Gradle An Android build system that automates several build processes.

This automation means that many common build errors are less likely to occur. More info See in Glossary and Internal. Processing the plug-ins A set of code created outside of Unity that creates functionality in Unity. There are two kinds of plug-ins you can use in Unity: Managed plug-ins managed. NET assemblies created with tools like Visual Studio and Native plug-ins platform-specific native code libraries.

When you select this build system, Unity goes through the same steps as the Internal build system excluding resource compilation with AAPT, merging manifests, and running DEX.

Unity then generates the build.
