Introduction to Advanced Light (Sky light)- 3Dsmax 5
In 3dsmax release 5 Lightscape render joined the 3d engine to improve the
power of 3dsmax. Now you can use radiosity without plugins of fakeosity.
First, you may construct a simple scene, with simple objetcs, floor and a camera
to test how the light works.
works. Go to the menu Create>Lights>Photometric. You will see some of the new
features of the 3dsmax5.
Choose the IE Sky. The Multiplier will define the strenght of the ligh, while the Sky Color
the color of the light and "clear, partly cloudy, cloudy" should set how it will come.
Click and drag it in the viewport, to set where the sun is
So you can go to the menu Rendering>Advanced Lighting
Select Light Tracer
Let's see some settings:
the Color Bleed, will define the reflection of the object light
the Bounces will define how much photons will bounce in the scene
high values means lighter scene and more time rendering...
The sky light will create a diffuse illumination like above. If you want more
strength, try change the values of the multiplier on the sky light menu, bounces etc.
Same configuration, but bounces values is 2. Note the softer shadows.
Now let's see a tip to get a better results
The multipier here is 0,5 instead of 0,35 of the other examples.
The shadows get a bit of noise, it's because of the Initial sample spacing
look again at this image
The initial Sample Spacing is 16x16, subdividing down to 1x1
If you want more quality (and more time to render) you can set instead
of 16x16, 1x1, then it will look like this:
Of course you can set the values between 16x16 and 1x1 to get intermediary results
if do you want to see how the photons are working on the scene enable the Show Samples box
That's it.
