I have a simple sphere. Half of it has an anisotropic BSDF material, the other half has a Principled BSDF material with anisotropy. I believe I have the same settings for the two materials, but they render differently. How do I get the materials to match?
Compared to the Anisotropic BSDF node, the direction of highlight elongation is rotated by 90°. Add 0.25 to the value to correct.
