Since a few days ago zbrush started warning me that it will delete undo history.
I have plenty of hard drive space(100s of GB) I have 32G of RAM. I have been playing with undo settings since and have tried everything. My undo history is set to 10000! Max undo size is set to 25G, I’ve tried “warm me when deleting” setting it to 10 and then 2000, enable saving is on. optimize is on and reserved undo memory is set to 2.5. There is no help docs for “reserved undo memory” when you click control. though it is still deleting all undos past 8 or so.
This has plagued my modelling where I find myself with a few very important undos being deleted which gfive me no choice but to close and not save my work and start again.
Any idea what is going on?
