The image will come out completely black because Color Tint in Tone Mapping controls is set to black

This message is caused by having “Color tint” value in Render Setup > Camera> Edit Tone Mapping > Tint set to complete black (RGB 0,0,0).

At such circumstances, your scene will always render black regardless of scene setup, as the color tint setting multiplies the whole image by the given color (any value multiplied by 0 = 0).

Possible causes:

“Color tint” in tone mapping controls is set to black.

Solutions:

Set “Color tint” value to some reasonable, bright color.
