The Lightning Viewer is now supported on both computers and iPads. This allows you to open and review models directly on your device, whether you’re on the go or at your desk.
Note: Textures are not supported on iPadOS 18 or earlier. On older versions of iPadOS, some browser feature flags may also need to be enabled for the Lightning Viewer to function properly (see details below).
