Hello!
I noticed that many of the assets that are in the threejs repository don’t have a proper license. I opened an issue and am tracking the progress to get these assets to have a proper license: Require media licenses · Issue #23089 · mrdoob/three.js · GitHub
If you have ever included a 3d model, bitmap, etc in a commit to threejs, or know about the assets, please consider contributing to the discussion in the issue.
