Corona renders black screen! - C4D
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 Cinema 4D.
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.
Note: With the introduction of new volume resolving in Corona 10, scenes where the camera is inside a non-enclosed volumetric medium (like a flat plane used for walls or ceilings) may render black. This occurs because the renderer interprets the camera as being inside an infinite volume.
To learn more and troubleshoot this issue, see: My rendering is very dark or black, I am having issues with reflection and refraction!
- Color tint ( Render Settings > Camera/Exposure/Tone Mapping > Tone mapping > Color tint ) in your scene is set to black
Solution: change the tint to a brighter color, i.e., white.
- Corona Renderer is not set as the default renderer.
Solution: change the default renderer. Render Settings > Renderer > Corona.

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".
