If you have limited RAM or video memory, Blender's undo and redo may not work. Insufficient RAM or video memory is the most common cause when you fail to undo or redo your changes omplex scenes require more memory to render and when you run out, Blender will stop keeping your older changes. All these options allow 3D Artists & Photo Editors to customize their workspace according to their need and skill level, helping them work faster & more efficiently without reaching maximum limits too soon. Under Advanced settings, you can change Memory Usage Limit (how much memory an operation uses) and Active Steps Threshold (this determines how long before older undo requests get deleted). Click Apply Changes at the bottom of the page and restart blender to apply your changes. To save steps, go to Preferences > Editing > Undo & Depsgraph Query Limit (the maximum amount available is 512). 3D artists and photo editors working on larger projects don't have to worry about hitting their Undo limit. Why is increasing your undo limit important? Well, this allows you to go back multiple steps when making changes or correcting mistakes and to tackle larger projects with multiple smaller edits. You can increase this limit to improve your efficiency and workflow. Related: What is Asset Browser in Blender? How to increase undo limit in Blender?īlender's undo limit is normally 32, which isn't enough for most 3D design and Blender artists. This data can be used to see which objects have been modified since they were first created or selected. Details about each object, such as their creation and modification timestamps, will also be displayed. After that, your progression through time will be charted in a timeline along the side of the screen. The edit history of your project can be viewed by going to the Properties window and picking "Edit History" from the drop-down menu. When we need a quick'redo' in either mode, we open our context-sensitive pop-up menu, which shows different options depending on what mode you're in and what action you're taking. In object mode, we can move objects, but Edit mode gives us deeper controls like vertex move and face scaling. Objects can be edited in Object Mode or Edit Mode. This makes switching modes multiple times to complete a task faster and easier. With this pop-up menu, I can select rotate and adjust my angle on the fly. Say I'm editing an object and want to rotate it slightly without switching modes (Numpad0). This button brings up action-related options so you can complete your task faster. This saves time reselecting, moving, etc.Ĭontext-sensitive pop-up menu at the bottom left of the viewport is another great tool. Pressing "F6" to "redo last" in Blender is helpful if you make repeated changes, such as slight object rotations or face tweaks. If you want even more control over what gets reversed, the Global Undo option records all operations across all modes (Edit mode and Object mode) into a "Undo queue" so individual actions can be undone without breaking other related ones. The first controls how far back you can go, while the second limits how much memory your computer uses to track changes. Beyond this point, you can control your undo/redo preferences with Number of Undo Steps and Undo Memory Limit in the Preferences system section. "Undo Last Action" and "Redo Last Action" are useful for reversing simple mistakes. The most direct way of undoing actions in Blender is via the Edit menu.
