Sheen test model?

[bhouston]

I am noticing sheen differences between renders. Unfortunately we do not have any test models that show a range of sheen values (sheen, roughness) in a way that can lead people to do an analysis of where they have implementation issues.

I would suggest that we do a classic 4x4 sphere test with sheen? Along one axis, we range sheen from [0, 0.33, 0.66, 1] and on the other axis we range roughness from [0, 0.33, 0.66, 1]. I would suggest a blue base color.
