Interactive rendering is not working!

If you are experiencing similar problems:

  • Enabling docked interactive renderer results in "Click to start interactive session" message, but nothing happens after clicking on it
  • Nothing happens after pressing "start interactive" button from render setup ui, but CPU reaches 100% usage
  • Regular (non-interactive) rendering seems to work fine

this probably means that you have "Rendered Frame Window" option disabled in Render Setup dialog. Please see this guide for a solution: I cannot see Corona VFB!
