How to export a model as usdz compatible with apple vision pro native apps?
usdz exported from isaac-sim appear in apple vision pro to be empty.
On the other hand, usdz files originated for example from Polycam open and visualize using native Apple’s apps e.g. like Files[Quicklook]
From an OpenUSD point of view, USDZ is just a packaged USD, so any use of custom or experimental schemas (including various Gaussian representations from different tools) will not be reliably consumable across the ecosystem and may appear “empty” or partially missing in downstream apps that do not implement those schemas. Apple’s own tooling also produces USDZ variants (e.g., with Gaussian content) that are not considered baseline/standard USDZ at the moment, which further complicates expectations around “it opened fine in app X, so it should open everywhere.”
