3. Explanation of a new function of "Multilight"

The multilight is the most innovative and attractive function.

When this function is used, you can greatly shorten the amount of time you

spend for lighting and rendering your scene.

Above you can see the scene preparations before using the multi light function.

Object name Material name
Sphere jewels->Gold_ok.mxm
Teapot jewels->Silver_ok.mxm
Torus Knot jewels->copper_ok.mxm
Hose rough metals vol.1->CyanLMetal,mxm
Shade jewels->Aluminium_ok.mxm
Room Default
Floor Default
Bulb Default (Don't adapt Emitter yet)

In the render settings turn off "Physical Sun"

and turn on the "Multilight" option.

(The materials of the light source)

From left...

  • sodium low pressure 180w.mxm
  • metal halide hmi -2500w.mxm
  • sodium low pressure 135w.mxm
  • metal halide hmi -1200w.mxm

Adapt the first material to your light bulb on the very left and continue

to add the materials in this sequence from left to right.

I did my renderings with the following settings.

  • Image size -> 480×360pic
  • Spent rendering time -> 60min
  • Sampling level -> 20
  • Last sampling level -> 13.50

You notice the scene was lightened by different coloured lights.

I recommended saving the present rendering results before you add multilight

to the scene.

Now select the Multilight tab inside the Maxwell stand alone interface.

You will now see 4 Emitter columns, each of them representing one light source

in your scene.

You can then adjust the Emitter values as well as ISO and shutter values with

the respective sliders.

You don't have to render the scene again! Simply click the refresh button to

apply the changes to your rendered image.

Sample of Emitter, ISO, Shutter settings

(Click to enlarge image)

ISO: 100
Shutter: 249
Emitter 0: 0
Emitter 1: 100
Emitter 2: 0
Emitter 3: 100

Red lights were turned off.

The scene became a little dark, and the shadow of the left ball has changed.

When the button "S" (I guess it stands for "Solo") -which is placed under

each Emitter- is turned on, only the effect of this light is calculated.

When you change the shutter value from 249 to 20 the image brightens up noticeably,

because now the virtual camera film is exposed 1/20s to the light and not only


This again is a good hint to see how accurately Maxwell Render mimics real

life circumstances.


Obviously Multilight is a lot more efficient than rendering the same scene

over and over again.

Remember, each render on my machine took about 1 hour!
