We’re in the process of trying to build a mobile app supporting ios / android using Autodesk feviewer rendering inside a WebView (react-native-webview) but we’re having a lot of problems with IOS devices.

The app is a React Native app which was scaffolded using expo.

Our models initially load (we’ve tried SVF and SVF2 formats).. After a short time or on attempting to interact with the 3d model, we receive an error: Web GL Context lost.

We were using the latest 7.x version of fe, we’ve recently tried bumping it down to v 7.99 as at is what we use in our current web products, to no avail.

I know there are a host of options / settings like useWebL2, progressiveRendering, gpuLimit, limitDeviceResources and setting memoryLimits. There are also things we can disable such as lighting and ground shadows… etc.

I thought I’d reach out to help to understand if there were any recommended settings, or changes we can attempt to get our models working, on the more recent ios devices without WebGL errors.

We are not seeing these issues on Android devices.

Any help appreciated.
