VRSG Scenario Editor

MetaVR's VRSG™ Scenario Editor enables you to create and edit real-time 3D scenarios to play back in VRSG. Within its game-level editor type interface you can add culture and moving models directly to your 3D terrain and build dense 3D scenes with 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 (MDS) 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.

Key features

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 in two ways:

  • In VRSG Metadesic, visualize the static culture content (such as buildings and trees) and 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 Metadesic from the Scenarios tab on the Dashboard.

  • Broadcast DIS from Scenario Editor and view the exercise in VRSG Metadesic. You can use Scenario Editor to perform live updates and create dynamic content on the fly. For example, in a classroom setting, an instructor can broadcast an exercise in Scenario Editor and the students can view the exercise in VRSG. Students can see immediately any updates the instructor adds to the exercise.

Scenario features

Scenario-building features include:

  • A timeline editor to sequence behavior entity movements and animations, appearance changes, effects, and camera views.
  • Explosions, smoke plumes, and other special effects.
  • 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.
  • Environmental parameters such as sun and moon position, time of day, fog, haze, and sky model.
  • Network options for scenario playback on a network, broadcast to specific VRSG channels.
  • Ability to import existing scenarios into a new, larger scenario.
  • 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.
  • 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 versions 6.1, 6.0, and version 5.11 releases are 160 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.

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.

What's new in version 1.5

VRSG Scenario Editor version 1.5 contains the following new features and enhancements:

  • Multiple selection of culture entities, for moving, duplicating, or deleting them as a temporary group.

  • Crater support as an effect for scenarios. Craters, which have been a feature in VRSG for some time, change the contour of the terrain, creating a hole in the terrain at a specified time with a specified radius and depth scale.

  • Improvements to the damage effects tool for culture entities.

  • Improvements to specifying altitude and elevation for entities.

VRSG Scenario Editor version 1.5 is installed with VRSG version 6.1. You can order VRSG directly from MetaVR.
