The top compression formats in Android are ETC1, ETC2, and ASTC. #Unity pc build what does compression method mean android Top texture compression formats with device penetration as of September 2020ĮTC1 is supported on practically all devices.
It has no transparency support games can use a second texture for the alpha component. It has quality issues with sharp transitions such as edges and text.ĮTC2 is supported by all devices that support GLES3. It supports multiple transparency modes and improves quality compared to ETC1.ĪSTC is a more recent format that's more flexible it supports many different kinds of textures, allowing for just about any texture in your game to benefit from compression. In addition, it supports various block sizes with different associated compression ratios. When experimenting with ASTC on Asphalt Xtreme Gameloft found that they could reduce the size of their game by up to 30% Using texture compression format targeting Using this format is a good way to optimize the size, image quality, and performance of your game. Once you've implemented Google Play Asset Delivery in your game, adding texture format targeting is an incremental step.
Inside your asset packs, make sure you have a directory that holds just your textures, such as /textures. Then, create additional texture directories with a suffix representing the additional formats you wish to support.įinally, update your app adle file to enable texture splits in asset packs: This directory will be used to hold default textures (probably in ETC1 or ETC2 format). #Unity pc build what does compression method mean update
Google Play strips off the texture suffixes so your game reads its assets from the default directory, regardless of what textures are delivered to the device. If you're using Unity, our Play Asset Delivery plugin for Unity is ready to create app bundles with texture-targeted packs. #Unity pc build what does compression method mean download.
