How to achieve this texture with bump mapping ?

[Anonymous]

Hi !

I've been struggling for days now to know how to get the kind of red bubble texture of the handle of the sword :

So I tried with my own bump map :

And, adjusting the specular, rougness and subsurface settings, I get this really bad result :

It doesn't look like bubbles and the sides are perfectly smooth while it should be done with little rounds instead.

How would you proceed, please, to make it work ?

Thanks ! 😄
