Windows, Linux, macOS, PS4, XBox One, Android (Nvidia Tegra and Intel Bay Trail), WebGL Crunch Textures can take a long time to compress, but decompression at run time is very fast.Ĭompressed unsigned normalised integer RGB Texture. Crunch compression helps the Texture use the lowest possible amount of space on disk and for downloads. Textures are decompressed to DXT or ETC on the CPU, and then uploaded to the GPU at run time. RGBA is a version of RGB with an alpha channel, which supports blending and opacity alteration.Ĭrunch compression is a lossy compression format (meaning that parts of the data are lost during compression) on top of DXT or ETC Texture compression. RGB is a color model in which red, green and blue are added together in various ways to reproduce a broad array of colors. The table below shows supported platforms for each compression format. In addition, all platforms have different hardware, and are optimised to work most efficiently with specific compression formats choosing non-compatible formats can impact your game’s performance. When this happens, time is lost decompressing Textures, and memory is lost because you are storing them twice. When you use a Texture compression format that is not supported on the target platform, the Textures are decompressed to RGBA 32 and stored in memory alongside the compressed Textures. Pixel lighting is calculated at every screen pixel.

Pixel size depends on your screen resolution. In the description below, see the final file size of a in-game Texture of 256 by 256 pixels The smallest unit in a computer image. Choosing a Texture compression format is a balance between file size and quality the higher the quality, the greater the file size. The following table shows the Texture compression format options available on each platform, and the resulting compressed file size (based on a 256px-square image). More infoĪll supported Texture compression formats The Unity WebGL build option allows Unity to publish content as JavaScript programs which use HTML5 technologies and the WebGL rendering API to run Unity content in a web browser. WebGL A JavaScript API that renders 2D and 3D graphics in a web browser. See in Glossary, XBox One Microsoft’s eighth generation video game console.

The following table shows the default formats used for each platform. Default internal Texture representation per platform To apply custom settings for each platform, use the Texture Importer to set default options, then use the Platform-specific overrides panel to override those defaults for specific platforms. Unity has certain default formats set up for each platform, but in some situations you may want to override the default and pick a different compression format for some of your Textures (for example, if you are using a Texture as a mask, with only one channel, you might choose to use the BC4 format to save space while preserving quality). However, on most platforms there are a number of different supported Texture compression formats to choose from. See in Glossary files are left in their original format, in your project’s Assets folder. You can also create some asset types in Unity, such as an Animator Controller, an Audio Mixer or a Render Texture.

An asset may come from a file created outside of Unity, such as a 3D model, an audio file or an image.

Only the converted Textures are included in your build your source Asset Any media or data that can be used in your game or Project. The various different platforms and devices available each have their own different proprietary formats.īy default, the Unity Editor automatically converts Textures to the most appropriate format to match the build target you have selected. 3D graphics hardware requires Textures to be compressed in specialized formats which are optimised for fast Texture sampling. See in Glossary by 3D graphics hardware such as a graphics card or mobile device. By default, the main camera in Unity renders its view to the screen. See in Glossary (such as JPG, PNG, PSD and TGA), these formats are not used during realtime rendering The process of drawing graphics to the screen (or to a render texture). Textures are often applied to the surface of a mesh to give it visual detail. While Unity supports many common image formats as source files for importing your Textures An image used when rendering a GameObject, Sprite, or UI element.
