Compressed Texture Workflow (glTF|Basis)

donmccurdy · July 27, 2020, 10:09pm

There will be a new workflow available with three.js r119. It’s still experimental (the Basis extension for glTF is not complete yet, and things may change) but it’s likely to be more useable than the older workflows described earlier in this thread. Please try:

Compress with gltf-transform etc1s ... or gltf-transform uastc ... using glTF-Transform CLI.
Test in https://sandbox.babylonjs.com/ or https://gltf-viewer-experimental.donmccurdy.com/.

Note that the --zstd option for Basis UASTC is not yet supported in my viewer, and I’m not sure if that support will make it into r119 or not. The PR is https://github.com/mrdoob/three.js/pull/19932. Once r119 is released I will update https://gltf-viewer.donmccurdy.com/ as well (and the experimental version above may stop working).
