Anisotropic Bug

[pandus2]

Problem - Anisotropic bug as a line

Cylindrical surface in any position = bug
(Bug shown on the top and bottom side of the object, relative to the axis Z)
Cylindrical surface along the axis Y = no bug
Flat surface = no bug
Spherical surface = no bug

HDRI or Light Source = bug

Sorry for my english :)

Isn't this line just the edge of the gradient map...?

[pandus2]

No, I thought so too.

This is without gradient, only anisotropy.

Bug also is.

[Ludvik Koutny]

I do not think that is a bug. It may also be limitation of current anisotropy implementation. Anisotropy is always world space, it does not support object space or UV space.

[pandus2]

Bad that it imposes restrictions on the visualization.

Tested the V-Ray.
The problem with anisotropy is also V-ray, but differently expressed.
