Hi.

This is prob a stupid post and I am quite prepared to be called stupid if
I get an answer.

I am trying to render the inside of our theatre. I want to be able to show
directors what their scenes will look like in various lighting states. However
I cannot get a blackout. When I remove all the light sources I still get a
picture. Not even a dark picture.

I would like to find out where the light is coming from and flick its switch.

So how do I get rid of the light please.

Thanks.
Eamon.

global_settings { ambient_light 0 }

  Or alternatively:

#default { finish { ambient 0 } }

Its probably ambient light.  Either:
1. set ambient_light in the global_settings block to 0
2. make sure to set ambient to 0 for your textures

I would suggest #2 as there are times when you do want to make use of ambient in
certain textures (e.g. making a visible light source that 'glows')

Follow the recomendation of Warp.

You should also check if you use ready made textures, mostly from some *.inc 
files. Some of those have some non-zero ambient values. The textures from 
metals.inc and golds.inc are big offenders.
It will be easy to spot after setting a default texture with ambient 0. Remove 
all lights and render. Any place that is still not black is using a texture with 
some ambient set to more than zero.

Thanks to everyone who replied, the switch has been flicked
and it is all dark.

Thanks again.
