Should I stop at GLTF or continue to GLB for a rigged asset?

Depends on the next hand: GLTF when the asset enters a pipeline that scripts or validates it, GLB when it goes to a person or a web page. The animation data is identical in both — this is a packaging decision, not a fidelity one.

My FBX used custom Autodesk shaders — what happens to them?

They map to glTF's metallic-roughness model as faithfully as their parameters allow, which usually means slightly different highlights. For marketing-grade visuals, tweak the converted PBR values; for web and AR delivery, the approximation is normally imperceptible.

Do I need to install software to change FBX into GLTF?

No. The whole conversion runs as a web page: the FBX file is parsed by your browser, rewritten to GLTF locally, and handed back as a download. There is no installer, no plugin and no desktop app in the loop.

What happens to no feature gaps at all on the way from FBX to GLTF?

Nothing is lost on this route — the GLTF format can express everything the FBX file contains, so the conversion is a faithful rewrite rather than a simplification.

Will the model look different after FBX → GLTF?

Geometry is re-exported as-is, so shape, scale and UV layout stay faithful. The only visible changes come from features the GLTF format cannot express — those parts of the material or setup are simplified to whatever GLTF can store.

Pipeline integration where rigged assets need to be validated, renamed or post-processed by scripts

Using the GLTF file afterwards

Run glTF validators over the export, batch-rename nodes in the JSON, or diff asset versions — then pack to GLB for delivery

FBX to GLTF moves rigged content out of the Autodesk box and into open, readable files: the scene becomes JSON, buffers become .bin sidecars, and textures become plain image files. Every clip and bone survives the trip — what changes is that the asset is now inspectable and scriptable, at the cost of managing a file set instead of one download.

What changes in the file

1
Ship the whole set: .gltf, .bin and textures only work as a folder
2
FBX unit scales (often centimetres) carry into the JSON — check that web viewers read the same scale
3
Materials convert to glTF PBR; legacy FBX shaders (Phong-era) map approximately, so eyeball the preview
