I need to show a 3D model on a SceneView in my iOS app, after its relative path (String) has been loaded from Firebase and passed to my SCNScene(named: path).
The function that reads the path runs very quickly, but once I try to attach the scene to my SceneView, it takes pretty long before it can actually be displayed (5-6 sec). The .scn file I'm trying to show is about 20MB, and if I set showStatistics = true, it says my scene contains more than 200K triangles.
I need a help in order to understand how I could strongly reduce the "loading" time of the scene. I've already tried reducing the number of polygons and also using the SceneView method prepare(_:completionHandler:) in order to render my scene on a background thread and (ideally) speed up the process to display it, but nothing worked for me. Any help would be really appreciated. Thanks!
