To Work with VRED Scene Files

Add a File to a Scene

You can add files of many types to VRED scenes; for example, other VRED scenes, XML or Python files, or files created by other applications, such as 3ds Max or Showcase.

1. Optional: Select a node under which you want to add the file or animation.
2. Click File > Add.
3. Select a file to add to the scene.
4. From the Merge Project Options dialog box, select the elements you want to import.

   These can include variants, touch sensors, sequences, and as of version 2016 SR1, animation curves and clips. You can also add or merge enviroments.

The file is added to the Scenegraph as a child of the selected node. If there is no node selected in the Scenegraph, the objects are added as children of the root node. All objects of any added file are grouped in a group node. Imported files are marked green in the Scenegraph.

When merging projects, viewpoints are preserved.

Add an Animation to a Scene

You can add VRML animations to a scene, provided they include the objects being animated.

1. Click File > Add VRML Animation.
2. Select an animation to add to the scene.

Save or Publish a Scene

From the File menu, select the appropriate save option.

• Save or Save As: Save as you would other from other applications, using the supported VRED file formats:
  • VRED Essentials Project Binary: .vpe
  • VRED Project Binary: .vpb
  • VRED Project File: .vpf
• Save Selected: Save the current selection to a supported VRED file format.
• Save Package: Save the project with textures stored in a subfolder instead of inline.
• Publish: Publish a VRED project to a single file with a specified start and end date; the scene cannot be loaded outside of the specified date range.

Import Information to a Scene

You can import various file types and meta information to a scene.

1. Click File > Import.
2. Select the type of information you want to import:
   • Rendering Meta Data: Images rendered with VRED (.png, .jpg, .tif) contain Scene settings embedded as meta data in the renderinRendering Meta Datag. These settings are applied to the loaded scene.
   • CAD: Supported file formats: .apf, .asm, .catpart, .catproduct, .cgr, .dlv, .dlv3, .dlv4, .dwg, .dxf, .exp, .g, .iam, .iges, .igs, .ipt, .jt, .mdl, .model, .neu, .prt, .session, .sldasm, .sldprt, .step, .stp, .wire
   • Cosmo Binary: Cosmo3D/Optimizer Geometry .csb, Deltagen Geometry .rtx, Deltagen Animations .wrl, Deltagen Variants .xml
   • PLM XML: Imports product structure files with .plmxml file format.
   • Render Jobs: Imports jobs from Render module to the current scene. (XML Render Queue Description .xml)
   • Sequences: Imports arrangements from Sequencer module to the current scene (XML Sequencer Description .xml). A sequence setup for the sequencer module can be added to the scene.
   • Variants: Imports variants from Variants and Vsets module to the current scene (XML Variant Description .xml). A variant setup for the Variants and VariantSets module can be added to the scene.

Export Information from a Scene

Export various information from a scene, including geometry, images, sequencer batches, and variants.

1. Click File > Export.
2. Select the type of information you want to export.
   • Scene: Export the whole scene; supported export formats include:
     • VRML Geometry: .vrml .wrl
     • Wavefront Geometry: .obj
     • VRED Essentials Project Binary: .vpe
     • FBX Scene: .fbx
     • Maya® ASCII: .ma
     • Maya® Binary: .mb
     • Maya® Scene: .ma .mb .wire
     • FHS Geometry: .fhs
     • PovRay: .pov
     • OpenSG ASCII Geometry: .osg
     • OpenSG Binary Geometry: .osb
     • ProENGINEER Render Geometry: .slp
     • Python Script: .py
     • StereoLithography Geometry: .stl .stla .stlb
     • VRED Project Binary: .vpb
     • VRED Project File: .vpf
   • Selected: Export the current selection into one of the supported formats.
   • Switched Geometry: Export switched geometry data (*.osb).
   • CubeImages: Export the scene to a set of cube images. The export is based around a center point you create, such as with a standard primitive (which you hide using the Scenegraph). Cube Image render settings can be set in Preferences under Export.
   • Render Jobs: Exports jobs from the Render module to the current scene (XML Render Queue Description .xml).
   • Snapshot: Exports a snapshot of the viewport to the snapshot folder specified in Preferences.
   • Sequences: All sequences set in the sequencer module are in a separate xml file.
   • Variants: All variants and variants sets are in a separate xml file.

Optimize a Scene

Speed up rendering while lowering memory use.

1. Click File > Optimize Scene.
2. Select an optimization option.
   • Optimize Geometries: Optimize the geometry structure.
   • Optimize/Share Geometries: Optimize the geometry structure and try to share duplicate geometries.
   • Merge/Optimize/Share Geometries: Optimize by changing the Scenegraph structure.

Fore more advanced optimization options:

• Click Scene > Optimize to open the Optimize dialog box.
