 : Ericsson Texture Compression. Blocks of 4×4 pixels are compressed into a single 64-bit word. The 4×4 block is divided in half and each half is assigned a base color. Each pixel is then encoded as one of four offset values from the base color of its half. Android supports ETC1 since version 2.2 (Froyo). Defold compresses ETC1 textures.

 ## Compression types
 
 The following software image compression types are supported. The data is uncompressed when the texture file is loaded into memory.
 
 | Type                              | Formats                   | Note |
 | --------------------------------- | ------------------------- | ---- |
-| `COMPRESSION_TYPE_DEFAULT`        | All formats               | Generic lossless data compression. Default |
-| `COMPRESSION_TYPE_WEBP`           | All formats               | WebP lossless compression. Higher quality level results in smaller size. For hardware compressed texture formats PVRTC or ETC, the compression process transforms the compressed hardware texture format data into data more suitable for WebP image compression using an internal intermediate format. This is then transformed back into the compressed hardware texture format when loaded by the run-time. |
-| `COMPRESSION_TYPE_WEBP_LOSSY`     | TEXTURE_FORMAT_LUMINANCE TEXTURE_FORMAT_RGB TEXTURE_FORMAT_RGBA | WebP lossy compression. Lower quality level results in smaller size. WebP lossy type is currently not supported for hardware compressed texture formats. |
+| `COMPRESSION_TYPE_DEFAULT`        | All formats               | Generic lossless data compression. Default. |
+| `COMPRESSION_TYPE_WEBP`           | All formats               | WebP lossless compression. Higher quality level results in smaller size. |
+| `COMPRESSION_TYPE_WEBP_LOSSY`     | All non hardware compressed formats. | WebP lossy compression. Lower quality level results in smaller size. |
