Why convert VRPACKAGE to GLB?
Converting .vrpackage to .GLB is popular because GLB is the self-contained glTF binary that plays in web viewers, AR, game engines and model sites, while the SimLab container only opens in SimLab tools. One .glb packs geometry and textures together, making it the easiest way to share the models widely.
How to convert VRPACKAGE to GLB
SimLab Composer APP
Open the package with File > Open, then File > Export and select glTF (*.glb) to produce a single binary file with embedded textures. Available on Windows and macOS.
SimLab CADVRter APP
Load the SimLab content in the stand-alone CADVRter tool and export .glb directly, a lighter option than the full Composer.
Unzip then convert via Blender FREE
Rename to .zip, extract any packed .obj/.fbx payload, import it into Blender and use File > Export > glTF 2.0 (.glb).
About these formats

Open .GLB details →Quality & what to watch
- Interactive VR content (visual scripting, object actions, quizzes, annotations, start position) is discarded because glTF has no place for it.
- GLB embeds textures, so the file can be large; check size before using it on the web.
- PBR materials usually translate well, but complex SimLab shaders may look different in the target viewer.
