"WebTangent space mapping depends on the UV mapping of the object because the x and y direction in the texture defines two vectors of the tangent space (tangent and binormal) in world space. It is difficult and takes time to produce good UV mapping without seeing tangent space artifacts. What if we want to use a 3d grayscale function like Perlin noise? " - Tangent_space_rotation urp
