Convert FBX Models to MetaVR Model Format

3D models in FBX format can be converted to MetaVR's model format for rendering in Virtual Reality Scene Generator™ (VRSG™) with the free conversion utility that is distributed with VRSG.

MetaVR’s Fbx2Hpx utility converts a FBX-formatted model to MetaVR’s HPX model format. MetaVR’s support of Autodesk's popular FBX model format enables modelers to use a number of popular third-party modeling tools including Autodesk 3ds Max, Autodesk Maya, and Luxology Modo, to create models for use in VRSG. 

Using MetaVR's FBX model conversion utility.

MetaVR's FV510 model, in AutoDesk's Maya modeling tool, prior to exporting it in FBX format for conversion to MetaVR's model format, and resulting converted model in MetaVR's Model Viewer.

The Fbx2Hpx utility can also convert 3D models created in Esri City Engine. Modelers can export CityEngine culture models in FBX file format, and then convert them to MetaVR’s model format for rendering in VRSG.

Using MetaVR's FBX model conversion utility.

MetaVR's high-resolution (60 cm) city of Dubai in Esri CityEngine prior to exporting over 6,000 realistic 3D building models, in FBX format for conversion to MetaVR's model format, and resulting city rendered in VRSG. Terrain was built with MetaVR Terrain Tools for ArcGIS.

 USING THE CONVERSION UTILITY

To use the utility, enter Fbx2Hpx.exe at the command line, followed by the name of the model you want to convert, with or without any other parameters.


The creation of a switch mask for a new custom attribute in AutoDesk's Maya modeling tool for MetaVR's FV510 model.

A number of MetaVR-specific custom attributes (node names and properties) are supported by the FBX model converter to include node types that are needed for models used in visual simulation. Such attributes include DOF, LOD, rotation animation, collision mesh, and so on. You can add these custom node names and properties to KfbxNull nodes as needed.

 Converting character models

For converting human character models from FBX format to MetaVR's HPX model format, MetaVR also provides a character template. MetaVR's FBX character template includes an armature object containing a hierarchy of bones that matches MetaVR's BVH rig, as well as a low-polygon mesh that is used by VRSG’s physics.

The example below shows the preparation of a model in Autodesk 3ds Max prior to exporting it in FBX format for subsequent conversion to MetaVR's model format.


A character model in Autodesk 3ds Max prior to exporting it in FBX format, and the resulting model in MetaVR's model format, displayed in the Model Viewer.

After converting the model to MetaVR’s model format with the FBX2HPX conversion utility, you can inspect the model in MetaVR’s Model Viewer.

MetaVR's FBX model conversion utility (including the character template) is delivered with VRSG and is available to customers under active maintenance.

Note that attempting to convert a model that is in MetaVR's proprietary model format to another format is strictly prohibited by MetaVR's software license agreement.
