Hi all.I am fairly new to Zbrush.
Recently I try to paint on my mesh in edit mode together with Zadd.When I undo it only the Zadd be able to undo and the colour remain.Is that the actual behavior of Zbrush or i have my setting wrong.Even in the projection master mode, the problem still the same.hope to hear from you guys!!
thanks for helping in advance. 
Nope, no undo there. You have to make a copy of the texture (one button push) before your modifications if you are unsure if your actions are desirable…
cheers

U mean I cant undo it? This is no good as I am so use to the undo button in many software.You are suggesting I clone the texture before i make any modification? Thank you.
Yes, clone it. But you can also use the new ZApplink Script and then you can use any external 2D drawing prog which can digest .PSD files. Then you have all the undo’s you ever wanted.
Cheers

Ok.I have not tried zapplink yet.But it certainly excite me.!
