Are video textures supported?

I found some old posts and some “lab experiments” about Video Texture, but nothing recent.

Did video texture make it into Sketchfab or are they still “experimental” or in development?

It’s currently possible with the Viewer API, but not in the regular viewer.

How do you work with video textures? What software do you use? Are you animating UVs, or actually using a video file?
