Skin shading with Screen-Space Sub Surface Scattering

Hi three.js community!

I came across this quite incredible example of SSS: https://youtu.be/VKGnPno6kO4

I can see it was built in three.js but I can’t find anywhere any reference to the exact shader that was used - ‘Screen-Space Sub Surface Scattering’. Anyone have any insight?

I can find the simple SSS shader on three.js/examples but nothing like this anywhere.

Thanks, Taimur
