What's New in VRSG Version 7


What's New in VRSG

MVRsimulation has released Virtual Reality Scene Generator (VRSG®) version 7.0 with the following new features and enhancements, and 3D content:

  • New features in the Varjo HMD plugin include using Varjo eye-tracking capabilities for visualizing in VRSG, for real-time monitoring (on a separate VRSG channel in stealth mode) and in training mission playback for after action review. Such features (controlled in the Dashboard’s Varjo tab) include Enable Gaze Tracking which turns on tracking and pupil calibration, and Eye-Track Action Review, which inserts the headset wearer’s head position and pupil gaze data into the DIS stream. Other features include foveated rendering options for Varjo headset and the ability to render the VRSG scene in an external display in addition to within the Varjo headset.
  • The Eye Track Visualization option on the More Graphics Options dialog box turns on the rendering of the eye-tracking data (head position and pupil gaze) from a Varjo headset that has been captured in the DIS stream in a recorded VRSG session, as described above. Head position is depicted with  a head model and pupil gaze direction is depicted with red and blue cones.
  • New features in sensor simulation include: 
     - Built-in sensor fusion, enabling you to select two new possible sensor mode options: Visual Electro-Optic fused with IR White Hot and Visual Electro-Optic fused with IR Black Hot. You can control the fusion blend ratio by CIGI component controls or the slider on the Sensor tab of  the VRSG Dashboard. 
    - Use of a JSON file for creating a radiance profile of materials for sensor simulation. This means  you can now generate your own radiance profile either from IR Setup or from scratch in Notepad from a third-party sensor model or notional data. The IRSetup (under ITAR control) now produces an editable JSON file.
  • Ability to improve the appearance of dynamic cast shadows when viewing the scene through a narrow field-of-view (FOV), such as those typically used for UAV sensors. A narrow FOV induces high magnification and greater standoff distances, which can cause shadows to become washed out or to disappear entirely. Use the Shadow Quality checkbox on the Shadows tab to direct VRSG to render dynamic shadows at a higher resolution, for FOV angles below a given threshold. (You can find the FOV in use on the Dashboard's Graphics tab.)
  • 343 new models (including 240 new military models) have been added to MVRsimulation’s 3D model libraries since the previous release of VRSG in February, bringing the total count to over 8,920 models.
  • New support for multiple sizes of pageable textures: 512 x 512, 1024 x 1024, and 2048 x 2048 in 3D terrain built with newly released Terrain Tools v2.0. Terrain databases converted from OpenFlight source also benefit from multiple sizes of pageable textures with MVRsimulation's updated OpenFlight to VRSG terrain format conversion utility.
  • Remote Regeneration options Generator/Receiver on the Attach Offsets dialog box configure a given VRSG machine in UAV mode to transmit telemetry via DIS packets to a remote VRSG client machine.
  • Ability to attach a light lobe to a dynamic moving model via a JSON file.
  • The 2D sensor overlay AN/DAS-1 has been updated to AN/DAS-4. 
  • New SetPDU interface ATTRV_LOAD_MODEL_MAP supplies the directory of a specific ModelMap.ini to load.
  • New CIGI component control, CIGI_ComponentIdRotorWashParams, controls particle dispersion of a rotor wash effect: AGL height at which the effect begins, particle speed, and particle speed variance.
  • New CurvedDisplay plugin provides horizontal distortion correction for curved monitors.
  • New PixelShift plugin supports projectors that require a pixel shift for emulated 4K resolution.
  • VRSG has been recompiled in Visual Studio (VS) 2019. User-developed plugins built with  VS 2015 and 2017 will remain compatible with VRSG version 7.0.
  • In addition to the rebranding of the company name to MVRsimulation, this release includes a new naming convention for cultural feature files, viewpoint files, PDUlogs, sensor profiles, and microtextures is: vrsg.clt, vrsg.viewpoint, vrsg.pdulog, vrsg.irm, vrsg.json, and vrsg_microtexture_ x_y_z.tex. Previously created files with the older convention of "metadesic" filename are respected by VRSG 7.
  • Scenario Editor version 2.3, with full support for newly named vrsg.clt, vrsg.viewpoint, and vrsg.pdulog files. Previously created files with the older convention of "metadesic" in their name are respected.


MVRsimulation’s newest geospecific 3D dataset of Amarillio Airport, TX, was built using VRSG v7.0 and MVRsimulation Terrain Tools for Esri ArcGIS, version 2.0.

The terrain is comprised of 5 mm per-pixel and 2 cm drone imagery of the airport (14 sq km), 30 cm Maxar imagery of the airport, and 30 cm Texas Open Data (TRNIS) imagery of the Amarillo metropolitan area blended to 1m NAIP base imagery of CONUS++ terrain. The elevation source includes 70 meter elevation data of the airport blended to 10 meter NED data of Amarillo and underlying DTED-1 base elevation.

This terrain contains a substantial number of 3D culture models of the airport, such as two geospecific runways, helipads, runway lights, runway signs, a control tower, multiple hangars, and CityEngine-generated 3D culture of the city of Amarillo. The terrain was compiled in our round-earth terrain format for rendering in VRSG. 

This ultra-high-resolution terrain will be available on MVRsimulation’s CONUS++ South Central region 3D terrain in Q1 2022 and will be available to purchase by customers who are on active VRSG software maintenance and are US Government agencies or contractors (for official use only). The terrain can be viewed with a valid VRSG version 7.0 or greater software license with valid software maintenance.

  • Support for multiple blended microtextures, a new feature in the forthcoming MVRsimulation Terrain Tools for Esri ArcGIS version 1.4.  
  • Ability to increase (10x, 100x) or decrease (10x) the playback speed of a recorded pdulog or scenario built with Scenario Editor.  
  • Each screen capture is now saved with a corresponding viewpoint file, encoding the location of the screen capture in the scene.  
  • Improvements to VRSG's policy on handling the ground clamping of culture models.  
  • Scenario Editor version 1.6.

VRSG version 6.1, released in October 2016, put into the hands of VRSG users all the models in MVRsimulation's 3D content libraries at full resolution. The inclusion of 170 GB of 6,650 full-resolution models (including 179 new models since the release of version 6.0) provides the full benefit of rendering scenes in VRSG with MVRsimulation's highly detailed runtime models.

VRSG version 6.0, released in July 2016, contained several infrastructure updates, including full support for the Microsoft Windows 10 64-bit operating system, DirectX 11, Visual Studio 2015, and Nvidia’s new GeForce GTX 1080 gaming graphics card.

  • Full support for Windows 10 64-bit systems, to support customer integration efforts, in keeping with US Department of Defense (DoD) mandate for all the military services, Unified Combatant Commands, defense agencies, and field activities to upgrade their systems to Windows 10 by January 31, 2017.

    Click here for information about running VRSG 6 on Windows 7. (Note: Support for VRSG on Windows 7 ends on December 31, 2016.)
  • DirectX 11 support, which includes VRSG support for Pixel Shader Model 5.0. In addition, VRSG's plugin API now uses DirectX 11 objects. (Note: any user-developed custom plugin which drew graphics or otherwise interacted with the DirectX 9 Graphics API under VRSG version 5 will need to be modified to use DirectX 11 with VRSG 6.)  
  • Built with Visual Studio 2015, which means that if a user-developed custom plugin extends VRSG's Dashboard interface with a property sheet, the plugin must be rebuilt with Visual Studio 2015.  
  • Support for Nvidia’s GeForce GTX 1080 gaming graphics card, which delivers considerable performance enhancements.  
  • Solid particle effects, which model projectiles with dust trails being cast from detonation events. These 10 new ballistic effects, located in VRSG's \Effects directory, all spew solid particles. Some effects thrust particles in a given direction that is denoted in the filename. The release also includes a new billboard flame effect.  
  • Heat refraction post-processing effect for sensor views. This feature, available both on the Sensor tab of the VRSG Dashboard and via a fixed-length SetDataPDU interface, adjusts the simulated heat haze appearance of a scene when it is viewed through a layer of heated air (produced from conditions such as jet exhaust).  
  • A total of 169 new models (including 121 new military models) were added to MVRsimulation's 3D content libraries. Among the culture models is a set of 7 trees now available with variants for all seasons. The models tree-163, tree-164, tree-cassia-001, tree-cassia-005, tree-elm-002, tree-elm-006, and tree-poplar-004 now offer 4-season variants on their appearance switch states.  
  • Set of 14 high-resolution microtextures of a variety of dirt, sand, and grass geotypical ground textures. Many of the textures were newly created for this release. VRSG blends a microtexture with the geospecific terrain imagery to produce the most realistic visual depiction of the terrain when it is viewed at close range.  
  •  Scenario Editor version 1.4 with recent features that include the ability to assign damage effects to culture entities.  
  • MVRsimulation’s tool for converting models from FBX model format to MVRsimulation format now supports new direction properties for the Rotating Animation custom attribute. DirectionX, DirectionY, and DirectionZ are three distinct properties that define mesh rotation around an arbitrary axis other than a primary axis.  
  • Multichannel support is now part of the single unified VRSG executable, enabled with a check box on the Startup Parameters tab on the VRSG Dashboard.  
  • Changed layout of the Startup Parameters tab on the VRSG Dashboard to improve specifying the location of terrain, models, scenarios and so on, for VRSG to load (VRSG's search path).
