Segfaulting when trying to load large .usd files #491
Description
Description
Loading this example USD scene (https://disneyanimation.com/resources/moana-island-scene/, the link to the USD version on that page) seems to cause Isaac Sim to segfault. Isaacsim reports that it gets 51% through the loading process, and then it seems to freeze up (at least, the progress bar stops). It maxes out all 32 cores during loading, but there doesn't seem to be too much RAM or VRAM pressure (~20GB VRAM free, >50GB RAM free). After freezing for a while (10-20 minutes, all cores maxed out), it segfaults.
I wouldn't expect it to segfault under any circumstance. But I understand if there's some underlying file incompatibility or restriction on the subset of USD files that Isaac supports. Is there any documentation on what kind of existing USD files I should expect to be able to load?
