If an alpha channel or even wider support is needed, use RGBA Half. Its compression blocks can be compressed from 4×4 to 12×12 to less than 1 bit for each pixel. Can I ship the texture as PNG (to have a small build), then encode it to ASTC on the device (to have small memory footprint)?. Reload to refresh your session. See full list on docs. 4. After some digging, it sounds like all OpenGL ES 3. It will also report its format as “RGBA_ASTC6X6_UNorm”. It requires Vulkan or GL_KHR_texture_compression_astc_hdr support. If a device doesn’t support ASTC HDR the texture is decompressed at runtime to RGB9e5 or RGBA Half, depending on alpha channel usage. ASTC HDR is the only compressed format available on Android devices for HDR textures. If an Android device doesn’t support the texture compression format you use for a texture, Unity decompresses the texture at runtime. have a 16-byte header which needs to be stripped and are upside-down so -yflip needs to be used. However, there are no ASTC RGB-only formats in the GraphicsFormats enum which seems to be pretty exhaustive. Also, ASTC files produced by GitHub - ARM-software/astc-encoder: The Arm ASTC Encoder, a compressor for the Adaptive Scalable Texture Compression data format. unity3d. For devices that don’t support ASTC HDR, all devices running Vulkan, Metal, or OpenGL ES 3. Mar 10, 2020 · I was also asking this same question and this post was the first that came up, so replying for others who might be hung up on this. All ASTC textures are RGBA. ASTC is the most flexible format. You can use Unity in conjunction with most common You signed in with another tab or window. Aug 4, 2020 · LoadRawTextureData () is the correct one. As with low dynamic range textures, this is the most flexible format. com ASTC HDR requires Vulkan or GL_KHR_texture_compression_astc_hdr support. ASTC (8x8 pixel block in 128 bits) compressed RGB(A) texture format. This increases memory usage and decreases rendering speed. ASTC が推奨されますが、A7 デバイス (初期の Metal 対応デバイス) ではサポートされておらず、ランタイムに解凍されます。 サポートされているすべての形式の詳細については、 サポートされるテクスチャ圧縮形式リファレンス表 を参照してください。 unity 虽然也支持了 . Oct 14, 2022 · ASTC is for mobile. Apr 12, 2019 · You can put “Alpha Source” to none on a texture with no alpha channel, and the preview of the texture will still label it as RGBA. Jan 16, 2020 · We have plans to integrate the improved ASTC specific RGBM encoder into a future Unity version, but I don’t have a specific version yet. On the plus side, ASTC tools are 4-20x faster than its closest competitor, ETC2, for production output. Apr 10, 2019 · Adaptable Scalable Texture Compression (ASTC) is a form of Texture Compression that uses variable block sizes, rather than a single fixed size. After I changed the texture compression settings in the editor I saw a great size reduction in texture size, for 2k texture it is ASTC6x6 (1. You signed out in another tab or window. Notes on Android. If a device does not support ASTC HDR the texture is decompressed at runtime to RGB9e5 or RGBA Half, depending on alpha channel usage. ASTC is designed to effectively obsolete all (or at least most) prior compressed formats by providing all of the features of the others plus more, all in one format. Each block within the texture deciding whether to encode itself as RGB+A, RGBA, RGB, X+Y, or L component layout based on the content within the block rather than chosen by the user. Unless you’re targeting specific hardware (such as Tegra), ETC2 compression is the most efficient option for Android, offering the best balance of quality and file size (with associated memory size requirements). ASTC is an industry-leading texture compression format produced in mid-2012 after the emergence of OpenGL ES 3. ASTC HDR requires Vulkan or GL_KHR_texture_compression_astc_hdr support. You switched accounts on another tab or window. astc配列にASTC圧縮されたテクスチャデータが入っています。 Texture2Dにロードする LoadRawTextureData を使うことで、ピクセル単位ではなく生データとしてロードできます。 ASTC HDR requires Vulkan or GL_KHR_texture_compression_astc_hdr support. ASTC が推奨されますが、A7 デバイス (初期の Metal 対応デバイス) ではサポートされておらず、ランタイムに解凍されます。 サポートされているすべての形式の詳細については、 サポートされるテクスチャ圧縮形式リファレンス表 を参照してください。 6 days ago · Description. 0. 0 devices support ASTC, and all ARCore devices support OpenGL ES 3. 8 Mb) vs ETC2 (4 Mb Nov 8, 2017 · I’m using ASTC 4x4 and Fast during development, because my old 2015 Macbook Pro takes forever to compress the 8k atlases I’m using at Normal quality. Sep 18, 2019 · The ASTC format doesn’t differentiate between RGB and RGBA textures. After that, I decided to run some tests and if all is good then change the compression of textures in my project from ETC2 to ASTC to reduce build size. Feb 21, 2023 · Good morning, our adventure in the fabulous world on Unity WebGL brought to another unexpected problem! Tl;dr: why an ASTC compressed file downloaded via a UnityWebRequest (on a mobile device only) gives “WARNING: RGB Compressed DXT1|BC1 UNorm format is not supported, decompressing texture” when loaded into a texture? The long explanation: We created a platform for our clients to load One last note: ASTC compression takes time for best results. 0 support RGB9e5, which is suitable for textures without an alpha channel. For now if you want RGBM encoded HDR cubemaps on mobile then please use ETC2 RGBA. Unity’s default texture compression format is ASTC. While Unity supports many common image formats as source files for importing your Textures (such as JPG, PNG, PSD and TGA), these formats are not used during realtime rendering by 3D graphics hardware such as a graphics card or mobile device.

More info See in Glossary to create builds that target platforms based on the texture compression 3D Graphics hardware requires Textures to be compressed in Mobile browsers with adaptable scalable texture compression (ASTC) set as the texture compression format. That optimizes VRAM usage for mobile, and adding some VRAM usage on desktop. Điểm đặc biệt của ASTC đó là nó sử dụng cố định 128 bit cho mỗi block, mỗi texture sẽ có kích thước khác nhau để đặt vừa 128 bit đó. ASTC can run in faster modes, generating lower quality results in short times, when you are testing and don't yet need or want production quality.
