1. Global Switches
2. Indirect Illumination
3. Environment
Please uncheck Hidden Lights and Default Lights 
under the Lighting section.
Hidden Lights means hiding the lights from the scene. 
It is used when the users don
'
t want to see any light 
while modeling in the scene. When uncheck the 
Hidden Lights
box
, 
those
hidden
lights
will
not
affect
the
V
-
Ray
render
. 
To
prevent
these
hidden
lights
affect
the
final
render
output
, 
we
recommend
you
uncheck
the
Hidden
Lights
first
. 
Default Lights means V-Ray built-in lights. Users can 
not see nor edit these lights from the scene. If one 
uncheck the Default Lights and does not check the GI 
below, the render will turn out totally black. 
We also recommend you check the Low thread 
priority under the Render section so that it won
'
t 
affect other program while rendering with V-Ray. 
Please check the On under the GI section. That turns 
the Indirect Illumination on, so called the Global 
Illumination. We will explain those green dot items 
more later.
Environment is to control the
contract
, 
color
, 
and
HDR
of
the
Global
Illumination
.
Please check the boxes before GI and Background.
Please adjust those three items then select the blue 
render icon on the top. You will get the image with 
Global Illumination. Compare to the image without 
Global Illumination, you can see the objects don
'
t 
have dark shadow because the objects get light from 
all around.
Open V-Ray Options window and pull down the Global Switches, Environment and Indirect 
Illumination taps as illustrated below.
