Don't panic, This can be fixed! Chance's are you are using an unsupported material that Corona Renderer doesn't recognize.
- Recreate the problematic material and replace it with a Corona material.
- Consider running the latest dailybuild and use our scene converter. (V-Ray only) Cinema 4D Dailybuilds
- Run Corona Tools plugin created by Robert Hitzer (Works with C4D and V-Ray materials only - See site for limitations)
