Poly supportYes. Poly recognizes valid Autodesk FBX scene files and makes supported geometry and scene metadata available.
Indexed by PolyYes. Poly indexes filenames and creates visual similarity information for supported 3D content; available metadata is shown in details.
Preview in PolyYes. Poly previews supported Autodesk FBX scene geometry and scene content.
Poly agentYes. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files.

What does model/x-fbx represent?

The model/x-fbx media type identifies autodesk fbx scene files, normally stored as .fbx. FBX is a scene interchange format available in binary and ASCII forms. It can carry meshes, materials, transforms, skeletons, cameras, lights, and animation, but compatibility depends on the producing application and FBX version.1

Opening and converting the format

Autodesk Maya and Blender are useful applications for opening or importing this format. Export to GLB for compact interactive delivery, or choose 3MF for additive manufacturing when its package model fits the workflow.

Support in Poly

Poly previews supported geometry, makes filenames searchable, and provides visual similarity for supported 3D content. Available mesh and scene metadata can appear in details. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files.

ConstructHandling
GeometryMeshes, normals, UVs, and scene transforms
MaterialsMaterial and texture assignments may be represented
AnimationSkeletons and animation tracks may be represented
Poly limitationVersion-specific or application-specific features may vary

Poly supports inspection and multimodal understanding; editing, simulation, and exact authoring remain application tasks.

Format context and alternatives

Kaydara created FBX for its Filmbox product in the 1990s; Autodesk later acquired the technology and maintains the FBX SDK and format ecosystem. 1 Choose glTF or GLB for interactive scene delivery, OBJ for simple mesh exchange, and 3MF for manufacturing packages when its optional metadata matches the workflow.
