About this extension
🪲 Known bugs
  • On Fennec (Firefox for Android) pages sometimes refreshes and the model is gone
    Workaround: Go to the previous page and reload the model
  • Simplify setting often does not work properly (good news: you don't need it!)
    Simplify helper from Three.js seems a bit buggy: Small models tend to loose vertices, large models tend to simplify slowly and freeze the page
