    The usual solution would be to use 3D noise functions, but Unity doesn’t provide those as included nodes, so you’d have to write those yourself. Could be done as sub graphs or as custom nodes if you’re using the latest Shader Graph.

    An alternative would be to have the UVs be mirrored, or to use two UVs that overlap and blend between the two along the seam.
