| Editing
various light properties in 3D Studio
MAX ( 3DS MAX ) - Tutorial / Lesson |
|
Let's
get to know the Omni light
parameters in 3D Studio
MAX ( 3ds max ) a bit
and edit them to make
the scene more realistic.
Shall we? First make Omni01
the current selection
by choosing it from the
Select by Name
tool. Now go to the Modify
Panel  . |
|
Inside
the various parameters for
Omni01 in 3D Studio MAX
( 3ds max ), locate the
Intensity/Color/Attenuation
rollout and click on the
White colored rectangle
to bring up the color chooser.
Choose a light yellowish-orange
tint as shown in the figure.
This color is the color
of the light that our Omni01
casts. Noticed the color
change of the light at the
right end of the teapot
in the perspecitive viewport
of 3D Studio MAX ( 3ds max
)? Also increae the Multiplier
value to 2.0
instead of the default 1.0.
Increasing the multiplier
value increases the intensity
of the light. Similarly
change the color and Multiplier
value of the second light
(Omni02) by selecting it
and modifying its properties
in the Modify panel. |

Perform
a Render in 3D Studio MAX
( 3ds max ) to see the results
of the changes. A yellowish
light is cast by both the
lights now. It is visible
in the brick base, but the
teapot shows only a slight
yellow tint. It is because
the chrome material has
a reflection map that overrides
the subtle color effects
of our omni lights. Noticed
the slight jagging at the
edges near the teapot's
handle in 3D Studio MAX
( 3ds max )? It is caused
by the low polygon count
of our teapot object. Select
the teapot and go to the
Modify panel
in 3D Studio MAX ( 3ds max
). In the Segments
property, increase
the value to 10.
The teapot gets highly refined
since its polygon count
increases. Perform one more
render to see the change. |

| Turning
on shadows for the lights in 3D
Studio MAX ( 3DS MAX ) - Tutorial
/ Lesson |
Did you notice anything missing
in our rendering results so
far? Yeah you guessed it right.
Shadows. Most types of lights
in 3D Studio MAX ( 3DS MAX )
has the ability to cast shadows.
But we need to turn them on
manually. Since shadows are
computationally intensive, 3D
Studio MAX ( 3DS MAX ) turns
them off initially. Here's what
we need to do to turn them on.
Select the Omni01 light and
go to the Modify Panel.
Inside the 'General Parameters'
section you will see the 'Shadows'
sub section. Check
the 'On' checkbox
to turn shadows on for the selected
light. Repeat the steps for
Omni02 to enable shadows for
it too.
There are different types of
shadows in 3D Studio MAX ( 3DS
MAX ). By default, Shadow
Map is the type of
shadow selected. It produces
comparitively simple shadows
but is computationally inexpensive.
It has the disadvantage that
it cannot simulate lighter shadows
that occurs when light passes
through transparent objects.
But for most applications Shadow
Map gives satisfactory solutions
in 3D Studio MAX ( 3ds max ).
When transparency is there,
we might have to go for computationally
expensive 'Ray Tracing' shadows.
Keep all these stuff in your
memory. We will get to know
all these in detail in advanced
lessons. Let's now render the
scene to see how cool it looks.
The rendering result is shown
below. Your's should look something
similar to this.

Congratulations
once again for having conquered
this much of 3D Studio MAX ( 3DS
MAX ) lessons yourself. You have
just one more Chapter to take
to get promoted to the Intermediate
Lessons. As I always
remind you, please make sure that
you understand everything before
you proceed furthur. Don't skip
pages out of curiosity. These
simple lessons are very essential
for mastering 3D Studio MAX (
3DS MAX ). Spend atleast thrice
as much time to repeat exercises
and experiment on your own , compared
to the time you spend for learning
a lesson. Then only these foundations
gets really clear in your mind.
So what's left in this Chapter?
Yeah still scenes are reaching
a climax. Lets get things moving.
Let's do some animation. Move
on to the Animation Fundamentals
in the next Chapter |
