How to make raised triangular pattern?

Hi everybody.

I’m trying to accomplish this raised triangular pattern(?), but I’ve hitting my head against a wall trying to find a way to make it.
I need to attach photo here to give you better image:

See those triangles in this mouse. So I want one part of my Sci-fi helmet to look like that.
I’ve tried putting alpha mask on, and then used trimdynamic and move brushes without any luck.

I’m fairly new with Zbrush, so please help me here.

Thank you.

Actually I would use an Alpha for that. There are other, more complicated ways, but an Alpha should be ideal.
