How to create the same texture in the following images?

enter image description here

It's a chocolate truffle with coffee beans texture.

Maybe try something like that:

enter image description here

It's a subdivided cube that I've sculpted a bit, then paint a b&w mask to get a factor between brown and light brown color, give it a bit of bump and a bit of glossiness:

Following @moonboot's recipe, I wanted a few more truffles, and not all the same. So, a bit more procedurally:

  • An Icosphere (to scale, at about 2cm.) is given Subdivision and a Displacement modifier, with a Voronoi texture, to give it nobbles:

enter image description here

  • The 'Feature Weights' give quite a lot of control over the Voronoi result, and it can, further, be put through a Color Ramp in the texture panel.
  • The displacement is made in 'Global' space, so the every truffle gets different nuts

enter image description here

  • The (Cycles) material uses an Ambient Occlusion node to pick up the surface features, and a little translucency with sub-surface scattering.

enter image description here

.. not perfect, but the principle is there..

    $\begingroup$ @ThomasWeller Yes. Apply the Displace modifier. Quick way, select all chocolate objects, and Convert To > Mesh. But that involves applying the Subdiv, too, for resolution. You could displace procedurally in the shader instead, if you needed to avoid too much geometry before render-time. Baking the displacement to an image is also possible.. and in his case, not too tricky, because the original is a sphere. (Subtract the normalized radius from the actual length of P in object-space, as an emission, and bake that.) $\endgroup$

    $\begingroup$ Hi Robin, i downloaded your file because your pics looked damn delicious, i opened it in 3.1, rendered view, and i got: [1]: i.sstatic.net/WAiaL.jpg do i have to tap on some magic button so that it looks like yours? or is it just because of my blender apple sillicone version? 😢 $\endgroup$
