What Portable 3D Assets Can Carry Between Virtual Worlds

A file can travel farther than its behavior

Moving a 3D object into another application can preserve its visible shape while changing how it behaves. A door may still look like a door but no longer open. A training instrument may retain its materials while losing the interaction that made it useful. Portability needs a more precise promise than this asset works everywhere.

Khronos describes glTF as a format for efficient delivery and loading of 3D scenes and models. It includes elements such as meshes, materials, textures and animations. That is a valuable foundation, but a file format should not be confused with every rule of the application that created the asset. Before exporting, identify which properties belong to the asset and which depend on the surrounding experience.
