Gold granulation approach ZBrush

kat_sta

Hey guys, I have some freelance work going for 3D print and client will need granulation on the object. I don't know much details yet, but he wants it to look hand-made so granules will have to be fairly uneven. I wanted to ask if any of you have experience in similiar work, or you have idea for approach. I was thinking of creating few IMM brushes with bunch of granules sticked together but maybe there is something more efficient going. Any help willl be appreciated, Thanks in advance!
