I cant reproduce this on a PG yet but I starting to investigate WebXR and I have a weird problem affecting one of my models. I am using the helpers to generate an XR environment and everything works fine on a PC browser but when running on a Quest or a Samsung Galaxy S7 I get an error in the ImportMesh function that says “unable to import… invalid index into function table”. This is before I switch to XR mode so it is probably nothing to do with XR but something with the model itself. Another model works fine in XR and the problematic model works fine on PC. Perhaps this is more to do with whether it is running Pollyfill or not???
Any ideas on how I can troubleshoot this? The model is Draco compressed so I could try without (but the other model that works is also Draco compressed).
