Good morning,
I am sorry for my question but I am still kind of a newbie with Babylon. I am trying to load an AR scene locally, but I can’t seem to be able to run it. WebXR incubation is already enabled on Chrome, and loading a simple Immersive AR scene isn’t giving any problem. Issues arise when the featuresManager comes into play, as in the Hit-Test example below, where the marker does not appear at all. I took this simple scene from this playground Babylon.js Playground , where everything works fine. Am I missing some imports?
Thank you very much.
