I set up the undo steps to 256. While working on a scene, I noticed I couldn’t undo much, and I then realized the system undo steps were back to 32.
I set up the steps to 256 again, saved the file. I also created a new empty scene, checked the undo steps which were indeed 256, saved the preferences again just in case.
When I re-opened Blender the undo steps were correct, 256. I continued working on the same scene. At some point, the steps were back to 32.
Am I missing something?
I’m using 2.93, and v3 Cycles-X branch with the same issue occurring in both cases.
I can’t seem to remember a similar issue with previous versions.
My only thought so far is that maybe an add-on is causing the problem.
