Convert FBX Models to MetaVR Model Format

FBX-formatted models can be converted to MetaVR's model format rendering in Virtual Reality Scene Generator™ (VRSG™) by using 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 within VRSG.

Similar to MetaVR’s OpenFlight to HPX converter, Fbx2Hpx.exe is a command-line utility that imports a FBX model and exports it as an HPX model.

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.

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.

For converting your 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.

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.
