Default lighting issue

[yzaroui]

Hello,
I am a new user.

I used a little scene (some spheres inside a closed cube : see attachement) and was expecting to get a black rendring since there is no light source.

I tried both rendering algorithms. The directlighting seems to introduce some light or to emit light from objects, and I get a beautifull interior image, which is bad, since I do not master my lighting.
The pathtracing algo gives a full black screen which is the result I was expecting?

So how to get the directlighting algo to make a black output for scenes with no light?

Thank you

you can control this by changing the AO distance parameter in the directlighting kernel.
