So basically i saved something i was working on as a ztool for i wanted to record a F History later on, but
the problem is it seems that after i save the project and exit zbrush then reopen zbrush and load my ztool mesh i notice that there is no History just the mesh as i finished it when i exited so can i consider my History so far deleted and never come back or…?^^
Saving as Ztool will not save your History undo. Insted you should save in File as a project and check you have the the UndoHistory button active.
oh thank you so much mate
