Questions
- Is my glTF file uploaded?
- No. The glTF is parsed and the USDZ is written by JavaScript in your browser tab. The file never reaches our servers.
- Will the USDZ look the same as the glTF?
- The geometry is identical. USDZ keeps materials and textures too. See the notes above for this exact pair.
- Is there a file size limit?
- Files up to 150 MB open, but very large models depend on your device's memory. Desktop browsers handle big files best.
