Same settings, different mesh, totally different result

[Jimmy Gunawan]

I am looking at bunny and O-dot example. Then trying to replicate the result using my own mesh (just monkey 3D from Blender), the Grey-Scott preset seems to be totally the same, but the result I am getting is nothing like the bunny, or the O-dot. It's really strange.

What did I do wrong?

The leopard example also is something that I would to happen on the monkey head, but somewhat not getting anything interesting, even after spending hours dialing the attribute.

Any hints or video tutorial? Thanks!

So far, I found the K parameter to be very sensitive, even 0.001 makes a whole lot differences.
