Runs fine in Editor, even with headset connected.
Deployed to headset. No crashes, just not showing in app.

The immediate problem is that Cesium for Unity isn’t able to load its native code. The most likely cause is that you’re targeting 32-bit Android. Cesium for Unity only works on 64-bit platforms. Be sure to target ARM64, not ARM7. This may also require you to switch from mono to il2cpp.
