This is a follow on question asked previously but how so I get this exact effect, (including the depth of the checker squares)

Checher bump map

Original question here.

It may be possible to do it procedurally but here is a way to do it with a normal bake:

  • Built your pattern, it's like half pyramids that merge each others. Use the Mirror modifier as it's completely symmetrical.

enter image description here

  • Give your object 2 Array modifiers to make a whole grid. Also add a Subdivision Surface and Shading Smooth it.

enter image description here

  • Now create a plane, put it above your grid, unwrap and bake the normals.

enter image description here

  • Use the normal map on the object you want. As your surface seems a bit glossy, mix a Glossy with a Diffuse, and don't forget to plug the Normal map in both these 2 nodes.

  • $\begingroup$ Just confirming that your comment "Use the normal map on the object you want" means I can use it on a sphere object, as in the example? Great answer BTW. $\endgroup$ Sep 5, 2019 at 22:59
  • $\begingroup$ It's not clear how it is mapped on your sphere on your picture $\endgroup$

  • $\begingroup$ Can I have a look at your mirror modifer setup please, I am trying to make use of the mirror modifier in the modeling, (not used it before) $\endgroup$ Sep 7, 2019 at 14:44

  • $\begingroup$ The answer is great, and I upvoted it. I think it would be better if you explained how you baked the map (I know how you did, but a lot of other people don't) :) $\endgroup$

Add a diplace modifier and apply a normal map to the shader to get the same bump effect.

Please refer to the screen.

  • $\begingroup$ This is not blurred checker texture in the displace, it is regular noise. $\endgroup$ Sep 5, 2019 at 8:45
  • $\begingroup$ I'm obviously miszsing something. But this doesn't quite look like the OP bump? $\endgroup$ Sep 9, 2019 at 11:47
