How to Open GLB Files in Unreal Engine

Import GLB into Unreal Engine, step by step

1. 1Check the fileA GLB is self-contained: geometry, materials and textures are inside the one file, so there is nothing else to copy.
2. 2Import into Unreal EngineContent Browser › Import (recent UE 5 versions read glTF through the Interchange framework; older ones need the glTF Importer plugin).
3. 3Check scale and orientationUnreal Engine works in centimetres and is Z-up. GLB files are metres by convention, so they normally arrive at the right size.
4. 4Check materials and animationGLB carries PBR materials and embedded textures and can carry animation. Look at the model under a neutral light before you build on it.

What comes through

Things to watch for
