hi there, dear zbrush users,
i got this error message in zbrush 4r6 and don’t know what it means and what i have to do? i can’t open my scene anymore to work on. is there maybe a way to clear the undo history without opening the scene? i really have to know a workaround to work on this project.
thanks in advance
david
Launch ZBrush and check skip loading of undo history. Try to open the file.
it worked thank you so much. but what is this AIList? :D:D:D
Did you email support? Maybe they will tell you. Glad you were able to open your file.
yes i e-mailed to support but didn’t get a answer for now. maybe in a few days i know more.
thank you, it worked
We’re now up to ZBrush 2021 and still have the same error with no idea as to how to remedy it.
Surely, 64GB of RAM is enough for a 16 million point mesh [CT scan data]??
Still happening (2021, September)
2022 , and still have this…
2022.0.5
Me too
Same here, accidentally clicked “ok” instead of “cancel” so Zbrush crashed. Lost 20 minutes of work 
Can’t remember running into this before and it’s just a 900K tool. Just upgraded to a 4090 though, maybe it’s related ??
