Convert REALITY to USD

QUICK ANSWER
Is it possible to convert REALITY to USD?
Yes - REALITY converts to USD.

Reality Composer exports .usdz, which is just a zip wrapper around USD plus textures. Unzip it with usdzip/any archiver to get the .usdc/.usda payload, or use usdcat or Reality Converter to write a plain .usd.

Why convert REALITY to USD?

A .reality file is Apple's Reality Composer scene format, and .usd is Pixar's open Universal Scene Description that the whole .reality/.usdz pipeline is built on. Converting to .usd gives you the editable, uncompressed scene for use in USD-native pipelines like Omniverse, Houdini or Maya.

How to convert REALITY to USD

Reality Composer + usdzip FREE

Export the scene as .usdz with File > Export, then run usdzip -d (or unzip it) to pull out the contained .usdc/.usda and its textures.

Reality Converter (macOS) FREE

Open the .usdz in Reality Converter to review materials; it and the underlying USD toolkit let you save the scene out as .usd.

usdcat (USD command-line tools) OPEN-SOURCE

Run usdcat input.usdz -o output.usda from Pixar's USD tools to convert the exported package into a readable .usda/.usd file.

Quality & what to watch

  • Reality Composer's interactive behaviors and triggers are not part of USD and are lost.
  • .usdz uncompresses to .usdc (binary) or .usda (ASCII); pick the .usd variant your pipeline expects.
  • Texture paths may need fixing once files are extracted from the archive.

Frequently asked questions

Is .usdz the same as .usd?
Not quite. .usdz is a zip package containing USD files and textures; unzipping it gives you the .usd/.usdc/.usda inside.
Can I just rename .usdz to .zip?
Yes, .usdz is an uncompressed zip, so an archiver or usdzip can extract the .usd payload.
What reads the resulting .usd?
USD-native tools like NVIDIA Omniverse, Houdini, Maya and Blender's USD importer.
Do I lose anything converting to .usd?
Geometry, materials and animation stay, but Reality Composer scene interactivity does not exist in USD.
