Sculpting rocks

Is there any way I can mimic the ZBrush brush in this video? I haven’t been able to get any good looking results, and I suppose a similar brush would help.

It looks a bit like taking the Clay Brush then setting this for the curve

Then using a texture with alpha like the simple one i attach to this post, set to angle “Rake”

And using a high poly (or high level of multires) model as it does not work any good at all on anything not high poly enough.
Probably tweaking some more settings could help.
But as said “a bit like this” because the zbrush brush is obviously much better from what i see in the video than what is obtained with that.
