I have been looking at this painting for a while trying to recreate the red fabric material on his hat and poncho (not sure what the name is, but it looks like a poncho) from what i can tell it is some kind of velvet type material. I have found that a color ramp with layer weight as factor does provide an ok result to achieve the high lights effect. but I'm sure there must be better more realistic ways. Thanks in advance for any help! EDIT: this needs to be a shading setup that works in EEVEE.
