Always glad to share findings in this friendly community!.
I got a question for you gentalmen and I figured its better to ask then simply hold it in and not look ignorent. I keep hearing people in thsi fourm saying you can always “wiki” a term. Now I have tried going to wikipidia.com to past the term in the search engin and find nothing come up dealing with the term and ZBrush. So if I might be so bold to ask the exsperts here but what do you meen when you say, “the _____ brush, witch you can wiki for more info, can be used to…”
And now comens the grilling… :o and ty for you help agene, its ppl like you guys that give ppl like me hope in becoming what I always wanted to be, a fantastic modeler/texture artist.
