**Description:** - A-Frame Version: master branch - Platform / Device: desktop - Reproducible Code Snippet or URL: any, just use master <!-- If you have a support question, please ask at https://stackoverflow.com/questions/ask/?tags=aframe rather than filing an issue. --> One thing that helps is just switching to using `MathUtils` ```js THREE.Math = THREE.MathUtils; ``` But there are other issues as well.
