The small insets feature a few of the tools for working with 3D content: culture palettes of airfield and vegetation models, and a Model Viewer close-up of one of the building models used in the scene.
VRSG Scenario Editor enables you to create and edit real-time 3D scenarios to play back in VRSG. Within Scenario Editor's game-level editor type interface, you can add culture and moving models directly to your 3D terrain to create dense 3D scenes; you can also build pattern-of-life scenarios.
The graphical interface provides tools and content libraries you can use to build dense 3D scenes with realistic visual characteristics and pattern-of-life scenarios. Experienced VRSG users and novices alike can work in a flexible manner with the tools and content libraries to increase the realism of terrain easily with rich culture and scripted movements of vehicles and characters.
This application is installed with VRSG at no additional charge to MetaVR customers on active maintenance. Scenario Editor requires the Windows 10 operating system (64-bit) and supports terrain in MetaVR’s Metadesic round-earth format.
Scenario Editor is ideal for:
- Populating virtual worlds with 3D content quickly.
- Creating and sharing tactical training scenarios.
- Avoiding terrain correlation and model overlap problems by using the same terrain and 3D content in the scenario creation tool as rendered in the image generator.
Because Scenario Editor contains a 3D terrain workspace, you see exactly what you would see in VRSG. This means you can work with accuracy and precision in placing and refining your static culture and in scripting the movements of vehicles and characters, in environments such as dense urban scenes, airfields, and forward operating bases. For example, you could create UAV training exercises ranging from basic eye-in-the-sky scans to squad route reconnaissance race track scans to target identification.
Many aspects of Scenario Editor are familiar from VRSG, such as viewpoints, static cultural and dynamic models, effects, appearances, cultural feature files, and manipulating characters with weapons and animations.
The scenarios you create can be run in both Scenario Editor and VRSG. Any changes you make to a scenario can be put to immediate use in the VRSG simulated training environment. And you can easily update training areas of interest on the terrain across shared scenarios or just for a specific scenario.

Scenario Editor‘s key features include:
- Easy graphical user interface enables quick ramp-up time for new users.
- Position and edit static culture in a scene, in a WYSIWYG manner.
- Changes are updated in the 3D scene in real time.
- Navigate with a mouse or 6-DOF controller with panning, zooming, and orbiting.
- Choose 3D content from feature palettes with a search capability and gallery views.
- Set predefined viewing locations (viewpoints).
- Generate culture and scenario files that are compatible with the latest version of VRSG.
Using scenarios in VRSG
In a VRSG networked environment, you can run the scenarios you create with Scenario Editor by visualizing the static culture content (such as buildings and trees) and the recorded DIS entities. In Scenario Editor you can export a scenario’s cultural feature file, PDU log, and other associated files of the recorded activities of dynamic entities. Play the scenario in VRSG from the Scenarios tab on the VRSG Dashboard.

Scenario Editor works as a complement to MetaVR’s Terrain Tools for ArcGIS, which enables you to build 3D terrain from imagery and elevation and shape file data sources. Scenario-building features include:
- A timeline editor to sequence behavior entity movements and animations, appearance changes, effects, and camera views.
- Explosions, smoke plumes, craters, and other special effects.
Creating a crater in Scenario Editor, which is an effect that deforms the terrain. You specify the crater’s location, the radius, depth scale, and deformation start time. The resulting crater is shown in textured and wireframe views.
- Camera view control with viewpoints you can add to the timeline with a set duration.
- Playback controls to play, fast-forward, rewind, pause, and stop the scenario.
- Network options for scenario playback on a network, broadcast to specific VRSG channels.
- Ability to export shapefiles. A shapefile is the footprint of a culture model on the terrain. For each culture entity in the scenario, Scenario Editor exports a set of shapefiles in the standard shapefile format for use in applications such as Battlespace Simulations’ (BSI’s) Modern Air Combat Environment (MACE). You can also export cultural feature (CLT) files for use in BSI’s MACE for transformation into DIS entities.
- Multiple selection of culture entities, for moving, duplicating, or deleting them as a temporary group.
- Support for inserting 2D "overlay" images into a scenario that display at specified times. Such images can be used for annotations, textual instructions, title screens, or photographs.
- Support for DIS damage appearance states in culture entities. Damage states for culture are handled in Scenario Editor as effects. Included in VRSG are over 300 models in the culture libraries that have the standard slight, moderate, and destroyed damage states. In addition to using these models to depict destruction in scenarios, you can use your own models that have damage appearance states.

What's new in version 2.0
VRSG Scenario Editor version 2.0 now shares the same graphics engine as VRSG; the legacy graphics engine of previous releases of Scenario Editor has been replaced. Shared graphics and terrain loading between Scenario Editor and VRSG mean that terrain and models are still correlated, but will now look the same in Scenario Editor as they do in VRSG, and clamping settings in Scenario Editor are maintained in VRSG. Scenario Editor sensor modes and UAV overlays, as well as effects, 3D oceans, shadows, and clouds, will now match how they look in VRSG.
Major features in this release are:
- Scenario Editor is now an integral part of the VRSG installation.
- New Scenario Editor Dashboard provides access to settings that were never before available in Scenario Editor (like sky, shadow, and oceans settings) and settings that were previously located on other menus (like screen capture and environment settings).
- As a result of the merged codebase with VRSG, visuals in Scenario Editor now match VRSG.
VRSG Scenario Editor version 2.0 is installed with VRSG version 6.4.
