HI guys i’m just got my Zbrush4 … so i was scuplting a ****roach i got carried away …sculpting details and stuff…i step decimal the polys down from 200K to 21 k poly count … the shape was still there , alright with it … then i went to uV master to clone and unwrap … did the copy and paste the UV to the new PM created( the one with the 21 k poly count) … then i realise one thing … i can still continue sculpting with other brushes … but not standard brush i 've tried changing the strokes and alpha … but to no avail … is there an explanation of this … really appreciate feedbacks froms gurus here thanksss
