The Universal Render Pipeline (URP) is a Scriptable Render Pipeline that is quick and easy to customize, and lets you create optimized graphics across a wide range of platforms. If you want to do texture compression in-game, use Texture2D. However, as raised by recent studies, evaluating the quality of compressed textures is a difficult problem. We're adding support for compressed textures to Cesium 1. The system supports both 2D and 3D textures, at both standard and high dynamic range, at bit rates ranging from eight bits per pixel down to less than one. Abstract. If Unity needs to access an Asset from an LZ4 archive, it only needs to decompress and read the chunks that contain bytes of the requested. Description. DXT compression is all about interpolation, or gradients if you will. ETC ( Ericsson Texture Compression) is a texture compression format originally designed on the principal that the Human ocular system (your eyes) is much more perceptive to differences in luminance (brightness) than chrominance (color). The format that Unity compresses the texture to depends on the platform, and the properties of the texture. Compression artifacts in individual textures are likely visually masked in final rendered images and this masking is not accounted for when evaluating individual textures. ATC - Is effectively a small variation on S3TC. In addition, at the end is a more detailed walk through of some real-world compression testing results. Our method takes advantage of the locality of facial texture differences by blending a few textures with spatially different weights. It supports a variety of different texture formats and allows displaying Block Compression (BC) support for textures has been extended in Direct3D 11 to include the BC6H and BC7 algorithms.
