  • Scenario Editor version 2.2, with improved PDU log export process, ability to export cultural   feature files and viewpoints separately, full support for sensor, 3D oceans, dynamic shadows, and model attribute JSON files.


Version 6.5 is the last version of VRSG that will support Windows 7.


MVRsimulation’s newest geospecific 3D dataset of Spain was built using VRSG v6.5 and MVRsimulation Terrain Tools for Esri ArcGIS, version 1.6.

The terrain was built from 0.50 meters per pixel (mpp) resolution source imagery and SRTM1 (30m) elevation source data covering the entire country, including procedural bathymetry of the northern/western Spain coastline.  

It also includes high-resolution culture insets of:

  • Lugo province in the Galicia region of northwest Spain, built with 0.25 mpp imagery and 5 meter elevation source data;
  • Leon province in northern Spain, built with with 0.40 mpp imagery and 30 meter elevation;
  • Los Llanos Albacete Air Base (LEAB) located in Albacete province in central Spain, built with 0.40 mpp imagery and 2 meter elevation of the air base.

  • 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 MetaVR 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).
