v3.0.0

✋Breaking Change

• The KHR_materials_pbrSpecularGlossiness extension is no longer supported (renders white), as it has been deprecated for more than a year. This should affect only a small number of our users, but we're giving it a major version to call attention. Our Editor now supports auto-converting any uploaded Spec-Gloss model losslessly to use the modern extensions. If you need to batch-convert, gltf-transform has an excellent utility function. #3997

Features

🆕 Added dynamic hotspots, which follow a point on the model's surface while it animates. These can be generated by the surfaceFromPoint method, which the editor now employs. #3981
🆕 Added animated texture support, for video, canvas2D, and Lottie animations, which can be loaded and applied to any texture slot using our materials API. #3886
