Thustrust: the bumps are a procedural texture, and the balls are seperate.
If you’re curious about the method the way i did this way;
created a Icosphere, copied it, then into edit mode, select all, delete faces and edges, seperate all loose parts.
This will give you a bunch of dots as seperate objects, select them all and press center new, then click on the copied sphere and press Ctrl-L and link to mesh data, now you have a spheres instead of the dots.
You can resize these in edit mode, as they all use the same mesh resizing anyone of them will change the rest, and you can repeat the first part again with each of these spheres.
hope some of that is helpfull
