Render engine: Bidir/VCM is not yet production ready - it does not support interactive rendering as well as many other features and can produce incorrect results.

This message will occur anytime you set rendering engine to Bidir/VCM as it is an experimental rendering engine that does not support many major Corona features, and is not suitable for production work.


Solutions:

  • Set rendering engine back to default (Progressive)
  • In case you are aware of the limitations of Bidir/VCM engine, and are using it for testing or to achieve very specific results, you can hide this message by clicking "Ignore similar messages” button in Error Messages window.
