I’ve run into this too. I’m Using Cycles, however it isn’t available.
I have however found that the Sheen BSDF has a description when hovering over it that I think elludes to it being a renamed Velvet BSDF? It appears to behave similary.
Moreover in the video, when Jonathan is adding in a shader, the sheen BSDF isn’t there.
Is this the case?
