Objects can be seen after turning off all lights : How to turn off ambient light in Blender/Cycles? I am unable to find the lighting option that would turn off the ambient lighting after turing off all lightings in the scene while using Blender Cycles.
What I mean is, if I turn off all the lights in a scene, the scene is still not completely dark - there seem to be still some ambient light.

Is there any way to turn this ambient light off so that it does not affect my lighting setup?

PS: I have noticed that if I use a HDR background for lighting and then disconnent the node from the world output - the scene becomes completely dark.
In Cycles, the Background is emitting light. This will affect all objects, which receive light.

In order for the ojects to not receive additional light, do one of the following.


Set the background color to black (0, 0, 0).
[or] Set the strength property of the Background BSDF to 0.0.
[and] Disable Ambient Occlusion.




If you don't want your background to appear black, the following node setup restricts the backgrounds visibility to camera rays.

You can also restrict the visibility of the background with the cycles settings. Uncheck everything except Camera under Ray Visibility and the background emit no light except to the camera.
