A Sample of the Aperture Blades = 3,Aperture Rotation = 60 deg, Aperture Ratio = 1.2, 256spp. We can see that the triangle Highlight on the sphere rotated and its shape became slightly elongated due to the non-uniform aperture ratio.

A Sample of the Aperture Blades setting at 3, 256spp. We can see that the Highlight on the sphere becomes a triangle.

A Sample of the Aperture Blades setting at 5, 256spp. We can see that the Highlight on the sphere becomes a pentagon.

A Baseline Sample of the Aperture Blades setting at 0, 256spp. We can see that the Highlight in the Microfacet Sphere is round.
