Hi @mvaligursky
Going back to this thread. Seems like the engine might have this fixed from the PR you merged but I’m still running into the error using the online editor. Even creating a new project from scratch displays the black screen when clicking going into VR (both in Firefox and Safari). Unfortunately I’ve always used the editor to build and have no experience with the engine to recreate the whole app. If the editor says it’s on 1.68.1, shouldn’t it be fixed? Am I missing something? Appreciate your help!

Steps to reproduce:

  • Open the Editor
  • Launch the preview from the editor in Firefox (or Safari)
  • You will see the presentation screen, click the VR button
  • You should see a black screen, even if you run the WebXR plugin

Thanks!
