Android’s mainstream compression format is In iOS 10, Apple added ASTC encoding to the system. Unity compresses texture on build time, and if the build runs on device that doesn’t support texture’s compression format, Unity decompress it by CPU and handle it as 32bit uncompressed. ASTC (4x4 pixel block in 128 bits) compressed RGB(A) texture format. The key to ASTC is that while it uses a fixed 128 bits-per-block, each texture can have a different size block fit in those 128 bits, unlike the fixed 4x4 block of prior formats. Contribute to coderling/astc_preview development by creating an account on GitHub. This gives some significant improvements in image quality compared to the older texture formats, even though ASTC also handles a much wider range of options. For some reason your suggested change could not be submitted. See Complexity has been steadily increasing, but now we’re finally going to tackle the end boss of texture compression, ASTC. This format allows you to choose between texture quality and size on a granular level: all the way from eight bits/pixel (4x4 block size) down to 0. ASTC: Use ASTC texture compression. ASTC, or Adaptive Scalable Texture Compression is the result of a fever dream which preview texture in format astc in unity editor.

PVRTC texture compression format has been a long time default, but did you know from A8 processor onwards the device now supports ASTC texture compression? (and Yes ASTC is not supported on A7 chip devices, so if you’re still targeting that, then using PVRTC might still be viable. In my awareness, 2021. 1 or Vulkan also support ASTC format, including: Qualcomm GPUs since Adreno 4xx / Snapdragon 415 (2015), ARM GPUs since Mali T624 (2012), NVIDIA GPUs since Tegra K1 (2014), PowerVR GPUs since GX6250 (2014). 0. The first "big" iPad with ASTC support was iPad Air 2. This is a very simple format consisting of a small header followed immediately by the binary Instead, ASTC, PVRTC, ETC2, and ETC texture compression 3D Graphics hardware requires Textures to be compressed in specialized formats which are optimized for fast Texture sampling. Unity iOS doesn’t support DXT textures. The astcenc compressor supports generation of images for all three profiles allowed by the ASTC specification:. 2 change the minimum iOS version to 13 so that it explicitly cuts off support for iPhone 5s, since no public change logs of 2021.
