A question about shader graph material

When I finished connecting the shader graph,I found the material on main preview would have a line splitting the sphere and it will make it look unsightly.
How should I solve this problem.
Thanks.

That is UV wrapping. If you put the texture into the matching model with correct UV unwrapping, it should look fine.
If you don’t unwrap anything, maybe use triplanar mapping?
