Corona renders black screen!

If Corona renders black screen only, this might suggest that:

  • There are no light sources in your scene
    Solution: add light sources (either light objects supported by Corona, or skylight)

  • Your license is not activated
    Solution: Activate Corona

  • Wrong materials are applied - this could happen for example if pure black materials were applied to geometry after importing it to 3ds Max.
    Solution: make sure that proper materials are used.

  • Some object, which is not visible in the viewport, is blocking your camera
    Solution: move the camera out of the offending object, or remove the object

  • Color tint ( Render Setup > Camera > Postprocessing > Color tint ) in your scene is set to black
    Solution: change the tint to a brighter color

  • You may have "Render selected" feature enabled (Render Setup > Scene > General Settings > Render selected) and nothing is selected in the scene.
    Solution: Select something in the scene to render, or disable the "Render selected" option.

  • A render region may be placed outside of the currently rendered frame. This can for example happen when using the 2D Pan Zoom Mode.
    Solution: Remove all render regions by clicking and holding over the Region button in the VFB, and then selecting "Remove all".
