# Objective - Support compressed textures including 'universal' formats (ETC1S, UASTC) and transcoding of them to - Support `.dds`, `.ktx2`, and `.basis` files ## Solution - Fixes https://github.com/bevyengine/bevy/issues/3608 Look there for more details. - Note that the functionality is all enabled through non-default features. If it is desirable to enable some by default, I can do that. - The `basis-universal` crate, used for `.basis` file support and for transcoding, is built on bindings against a C++ library. It's not feasible to rewrite in Rust in a short amount of time. There are no Rust alternatives of which I am aware and it's specialised code. In its current state it doesn't support the wasm target, but I don't know for sure. However, it is possible to build the upstream C++ library with emscripten, so there is perhaps a way to add support for web too with some shenanigans. - There's no support for transcoding from BasisLZ/ETC1S in KTX2 files as it was quite non-trivial to implement and didn't feel important given people could use `.basis` files for ETC1S.

|
## Default Features
|
|
|
|
|feature name|description|
|
|
|-|-|
|
|
|bevy_audio|Audio support. Support for all audio formats depends on this.|
|
|
|bevy_gilrs|Adds gamepad support.|
|
|
|bevy_gltf|[glTF](https://www.khronos.org/gltf/) support.|
|
|
|bevy_winit|GUI support.|
|
|
|render|The render pipeline and all render related plugins.|
|
|
|png|PNG picture format support.|
|
|
|hdr|[HDR](https://en.wikipedia.org/wiki/High_dynamic_range) support.|
|
|
|vorbis|Ogg Vorbis audio format support.|
|
|
|x11|Make GUI applications use X11 protocol. You could enable wayland feature to override this.|
|
|
|filesystem_watcher|Enable watching the file system for asset hot reload|
|
|
|
|
## Optional Features
|
|
|
|
|feature name|description|
|
|
|-|-|
|
|
|bevy_dynamic_plugin|Plugin for dynamic loading (using [libloading](https://crates.io/crates/libloading)).|
|
|
|dynamic|Forces bevy to be dynamically linked, which improves iterative compile times.|
|
|
|trace|Enables system tracing.|
|
|
|trace_chrome|Enables [tracing-chrome](https://github.com/thoren-d/tracing-chrome) as bevy_log output. This allows you to visualize system execution.|
|
|
|trace_tracy|Enables [Tracy](https://github.com/wolfpld/tracy) as bevy_log output. This allows `Tracy` to connect to and capture profiling data as well as visualize system execution in real-time, present statistics about system execution times, and more.|
|
|
|wgpu_trace|For tracing wgpu.|
|
|
|dds|DDS picture format support.|
|
|
|ktx2|KTX2 picture format support.|
|
|
|zlib|KTX2 Zlib supercompression support.|
|
|
|zstd|KTX2 Zstandard supercompression support.|
|
|
|basis-universal|Basis Universal picture format support and, if the `ktx2` feature is enabled, also KTX2 UASTC picture format transcoding support.|
|
|
|tga|TGA picture format support.|
|
|
|jpeg|JPEG picture format support.|
|
|
|bmp|BMP picture format support.|
|
|
|flac|FLAC audio format support. It's included in bevy_audio feature.|
|
|
|mp3|MP3 audio format support.|
|
|
|wav|WAV audio format support.|
|
|
|serialize|Enables serialization of `bevy_input` types.|
|
|
|wayland|Enable this to use Wayland display server protocol other than X11.|
|
|
|subpixel_glyph_atlas|Enable this to cache glyphs using subpixel accuracy. This increases texture memory usage as each position requires a separate sprite in the glyph atlas, but provide more accurate character spacing.|
|
|
|bevy_ci_testing|Used for running examples in CI.|
|
|
|debug_asset_server|Enabling this turns on "hot reloading" of built in assets, such as shaders.|
