[Corona] LightMix Is Black: Troubleshoot & Fix Render Issues

LightMix is Black

If you encounter a situation where the entire content of the VFB (V-Ray Frame Buffer) turns black when you switch to the Interactive LightMix render element, or if the LightMix tab appears black when you try to adjust the values, there are a few common causes and solutions to consider.

Cause and Solution

• Verify that the light intensities listed within the LightMix tab are not set to 0, and that their colors are not black.

• Check for any residual render elements that may be present in your scene from a different renderer. This might occur if your scene was originally created using a different rendering engine and subsequently converted to Corona. If you find such elements in Render Setup > Render Elements, removing them may resolve the issue.
