Sculped Rocks - how to?

Hello, can anybody tell me how to make sculped rocks and maybe advice sculped building tools? Thank you!

Try Cel Edman's Sculptypaint.

Cel also sells packs of sculpted rocks and caverns in world... can't remember location but should be easy to find with a search.

Almost bought a set of 1 prim staircases from there until I realised you could do it for free using his sculptypaint

EDIT: Technically 2 prim staircases cos you need to set scultpy to phantom and add an invisible ramp.

Natalia has posted some tutorials in her blog for a couple different applications.

Sculptypaint rocks!

It rocks for making rocks, too. Go to Stone Tool, reset to cube or sphere or whatever, hit the "Randomize a bit" a few times, smooth... play with the scale and bend buttons, randomize a bit more, etc.
