I'm trying the sheen parameter on the principle bsdf, but i feel like mine works different (maybe because a different blender version). Your sheen adds the effect that is mainly visible on the edges of your object while my sheen aplies this 'softer color' over the whole object equally. I have everything set the same as u but when i increase my sheen value, my whole object just gets lighter in color.
The sheen effect did work though when we did it with the velvet shader however. I just wonder why it doesn't seem to work with this bsdf.
Hope u can help, thanks in advance

What!?
That's not supposed to happen!
I've tested it in 2.80, 2.81, 2.82 and 2.92 and all give me a correct result...
What happens when you render on CPU?
