GLB, OBJ and USDZ: What's the Difference?

3D files come in several formats, and each format has strengths that make it useful for particular workflows.

GLB packages geometry, materials and textures into a convenient binary file. It is especially useful for web-based 3D experiences and real-time viewers.

OBJ is an older and widely supported format that remains useful when working with software that specifically expects OBJ geometry.

USDZ is closely associated with Apple's AR ecosystem and can be useful when the goal is an AR preview on supported Apple devices.

MoveX3D uses GLB as the straightforward export option while additional conversion formats can be used when a specific workflow requires them.
