Shader graph and line in Voronoi

[humble nebula]

How can I get rid of this line? I thought that since it's generative noise, there shouldn't be any problems like this.

it depends on the mesh uv

I think what you mean by generative noise would be one that takes in x, y and z coordinates and spits out a noise value. Such 3D noise used by plugging in the fragment position would not give any seams. As you are mapping the noise using the UVs, the lines appear where there are UV seams as sokilo pointed out. It doesn't matter whether you use procedural noise or a texture if you have discontinuities in the UVs (which is unavoidable unless you use a mapping that has overlaps and mirrored parts). The two ways to achieve seamless noise would be to either triplanar map the 2D noise or use proper 3D noise (unity doesn't have one built-in but you can probably find ones online or from the asset store)

Yeah really, my mistake. I created voronoi texture in material maker (as in video) and it works
