  • $\begingroup$ If the texture is not a seamless one you will see the edge. $\endgroup$

  • $\begingroup$ I guess it's worth mentioning that @brockmann's answer works because the Voronoi from the Blender node is 3D, The rendered surfaces are slices through mathematically calculated Voronoi 'chunks'. $\endgroup$

You actually don't need any UVs nor a seamless texture in this case.

The given texture is just a voronoi pattern, which can be generated on the fly in shader using the Voronoi Texture node. If you want a bump map: create a second voronoi node, set it's feature output to 'Distance to Edge' and keep 'Scale' and 'Randomness' parameters in sync by using a Value node:

Recommend have a look into the manual: https://docs.blender.org/manual/en/latest/render/shader_nodes/textures/voronoi.html

  • $\begingroup$ Thanks for the tip man, For now i used a seamless texture but would definitely keep this in mind next time i do voronoi textures. $\endgroup$ Commented Jun 10, 2020 at 14:28

You can't make a non-seamless texture seamless, but you can find workarounds by using photoshop, or another program to make the texture seamless. I would either find a new texture, or use another program to make it seamless. There aren't too many other options, but finding a truly seamless texture should be pretty easy.
