Hello!
I have troubles with all my subdivided objects, I have shading seems to my renders, positioned to all my UV shells borders.
I tested several options, the result is always the same
If you have a solution, thank you for your lights.
Best regards.
it seems like you use anisotropy attribute in shader, in arnold anisotropy makes a glare break at the seams uv borders, maybe @solidangle finally decide fix this in future release?
Because it stretches from the А4 core
there is a solution to this problem
need connect out color aiUtillity with normal mode or shading point to Anisotropy tangent in shader
