For instance sprite*.png matches the files sprite.png, sprite1.png and sprite_with_a_long_name.png. Patterns can be expressed using the following wildcards: * Matches zero or more characters. The paths are expressed as “Ant Glob” patterns (see for details). The Path Settings section of the texture profiles file contains a list of path patterns and which profile to use when processing resources that match the path. The General tab contains a checkbox item Enable texture profiles. You can turn on and off the use of texture profiles in the editor preferences. texture_profiles file and configure it according to your requirements.

The Basis Universal format is a high quality but lossy format.Īll images are also compressed using LZ4 for further reduction of file size when we store them into the game archive.Ĭompression is a resource intensive and time consuming operation that can cause very long build times depending on the number of texture images to compress and also the chosen texture formats and type of software compression.Įach project contains a specific. This format is transcoded at runtime to a hardware format appropriate for the current device’s GPU. Defold supports Basis Universal texture compression, which compresses the image into a intermediary format. You can select what software image compression is applied on the final texture data (compressed or raw) in the bundle archives. You should test your source material and experiment to get the best results. These artifacts are highly dependent on how your source material looks and what compression method is used. Since all available hardware texture compression is lossy, you will get artifacts in your texture data. Profiles are then tied to matching file paths patterns, allowing fine tuned control over what files in your project should be compressed and exactly how. In this file you create profiles that express what compressed format(s) and type should be used when creating bundles for a specific platform. The processing of textures is configured through a specific texture profile. This is because the graphics hardware is able to directly manage compressed textures without first having to uncompress them. But, unlike software compression, it reduces the in-memory footprint for textures. Hardware texture compression also reduces the storage size of image resources. However, the image files need to be uncompressed when read into memory so even though an image is small on disk, it can have a large memory footprint. This makes the the final bundle size smaller. Software compression (such as PNG and JPEG) reduces the storage size of image resources.
There are two types of compression, software image compression and hardware texture compression. Defold supports automatic texture processing and compression of image data (in Atlas, Tile sources, Cubemaps and stand-alone textures used for models, GUI etc).
