For example, if you had a filter that only included Actors with a particular tag, clicking it would cause those Actors to be excluded, and everything else to be included. When you hover over a filter, you will see a green or red bar on the left side, a checkbox, and a trash can.Ĭlicking the green bar will turn it red, which negates the filter, reversing its function. You can set favorite filters, and also save and load filters for later use. You can use single filters, or use filter groups to create more complex filters including AND and OR Boolean operators. The middle area of the Level Snapshot window contains the custom filters. You will see this as the Level Snapshot system recommending to remove the Actors to get back to the original state. If you rename a sublevel after creating a Level Snapshot, the Level Snapshot system will consider all the Actors in the renamed sublevel new, instead of existing changed Actors. If you want to use them with your Level, you will need to track them manually. The following Actors and Actor components are not tracked with Level Snapshots. This section describes known limitations when working with Level Snapshots. Level Snapshots associated with other Levels will only be shown when those Levels are opened in the editor. If you have multiple Levels in your Project, only the Level Snapshots associated with the currently open Level will be visible in the Level Snapshot window. New Actors added after the Snapshot was taken will be removed from the Level.Īctors removed after the Snapshot was taken will be added back to the Level.Īll Actor transforms will be reverted to their saved states.Īny changes to Actor properties will be reverted to their saved states.
When you restore a Level Snapshot, any changes to Actors made since the Level Snapshot was taken will be reverted back to the states saved in the Level Snapshot. Once you have one or more Level Snapshots created, you can reset all the Actors to their saved state by selecting the Level Snapshot and clicking the Restore Level Snapshot button. Similarly, the states of Assets (for example, Materials) are not recorded, so any changes to Assets need to be tracked independently using source control. All the Actors are recorded, whether or not they are currently visible in the World Outliner when the Level Snapshot is taken, so you may need to check Actor visibility when using Level Snapshots to set up a scene in your Level. Level Snapshots contain a record of all the Actors in the World Outliner as well as the state of their Components and properties at the moment at which the Level Snapshot is taken. If you rename a Level Snapshot before saving it, be careful not to overwrite it with another Level Snapshot, because the revised name will become the new default unless you change or revert it. (Optional) Enable the nDisplay Support For Level Snapshots plugin. In the Project Settings window, navigate to Plugins > LevelSnapshots. In the Unreal Editor, go to the main menu and select Project Settings.

In order to enable the Level Snapshot feature, you need to install the Level Snapshots plugin. Experienced users can construct custom filters using Blueprints to manage the restoration of Actors / Properties on the most complex Level setups and automate common project-specific requests. For example, you can choose to restore only the lighting from a Level Snapshots or the position of a single actor. Users also have the flexibility to selectively restore only certain Actors or Properties from a Level Snapshot in order to account for bespoke needs in the moment that can vary from one situation to the next. Level Snapshots are especially useful for Virtual Production, as they enable users to reset virtual environments to their starting position between takes as well as track per-shot changes that may occur during a shoot while preserving the base starting point of the Level. This can dramatically streamline complex setups and avoid duplication and management of multiple variations of the same Level for different scenarios. Level Snapshots enable you to save a particular configuration of the Actors in the World Outliner of your Level and instantly restore your scene to that state.
