I've made very basic experiments of combining a sound with a Sketchfab animation, here is an example: https://jsfiddle.net/g21v3zgd/20/embedded/result/
This seams like an obvious feature, but I was wondering how many of you would actually use it? The main question is that it's hard to make a soundtrack matching an animation perfectly. 3D artists are not sound designers. But an MVP of the feature could be to simply let you add a background sound (for example by simply pasting a soundcloud link), do you think this would be a valuable feature?
If yes, feel free to share your own test using jsfiddle like I did to combine Sketchfab + Soundcloud embeds in autostart mode.
Thanks for the feedback!
