Animation VModifying Lightwave Objects
Object Properties Properties dialogue
box Some neat tricks you
can do to your object Morph your object
into another object Change the way the
object appears Shortcut = p
Let’s Get Started Start up Lightwave
3D Select Load Object
(+) In the Landscape
folder, select Ground.lwo
Loading Objects Whoa, what
happened? When loading large
objects, Lightwave changes the grid size to fit the object on the grid
The camera moves back so it can shoot the large item
Scaling Things Back to Size
Select the Camera Check the settings
on the numerics Grid size jumped to
500 meters! Camera is back
from center nearly 5 kilometers from center
Scaling Things Back to Size
Select the View tab
In the Grid section, select Grid Size
Type in 2 and press OK
Now the ground really covers the whole space
Bring the Camera Back
Select the Camera In the numerics box
change the settings: X = 0 m Y = 1.75 m Z = - 8 m
This is raise the camera and back it up a little from center
Let’s Look at Something
From the Items tab, select Load Object
From the Animals tab, select Triceratops
Change your view to the Camera view (6)
Press F9 to see what you have so far
Clean Up the Lighting
Select the Light Switch to the Top
view (2) Using the Modify tab,
move the rotate the light so it’s lighting the dino better
Do another test render to see how he looks
How About Some Background?
Lighting is better, but he needs a backdrop
Select Windows > Backdrop Options
How About Some Background?
Lighting is better, but he needs a backdrop
Select Windows > Backdrop Options
Turn on the gradient backdrop
Do another test render
Modifying Object Properties
Under Objects, make sure Triceratops is selected
Click on the Properties button (p)
Modifying Object Properties
Select the 2nd tab Deform Morphing Displacement map Enable Bump
Modifying Object Properties
Morphing Change your object into
another object
Displacement map Warps your object based
on an image or texture map
Enable Bump Roughs up the surface of
your object
Add a Displacement Map
Click on the T button under Displacement Map T stands for Texture
Under Layer Type, select Image Map
Since our dino is mostly a cylinder, under Projection choose Cylinder
Under Image, choose Load Image
Add a Displacement Map
In the Reflections folder, select FractalReflections.tga
Change the Texture Amplitude to 0.5
Add a Displacement Map
Do another test render to check him out This displacement is
caused by an image and doesn’t change over time
Modify the displacement by choosing different Texture Axis
Add a Displacement Map
Render this frame (F9) and Save the frame as Displacement.jpg to the desktop.
Take a Picture for your Homework
Animated Displacement
Change the Layer Type to Procedural Texture
Change the Procedural Type to Ripples
Press the Play button to see how this displacement map changes over time
Animated Displacement
Change the settings: Texture Value = 0.05 Wave Sources = 1 Wavelength = 0.5 Wave Speed = 0.02
As you change these settings, watch what happens to dino!
Decisions, Decisions Once you have your
settings the way you like or don’t like, it’s time to choose Use Texture Remove Texture
Reset the Board At the bottom of the
Displacement Map dialogue box choose Remove Texture This turns it off for
now, but you can go back and turn it back on if you like
We are going to try out some other tricks for now
Render Tab Changes how the object is
seen on camera Or not seen if you like
Options Change to a solid color Make it semitransparent or
invisible Make parts of the object
invisible Whether it casts a shadow or
can have a shadow cast on it
Clip Map Makes parts of
the object invisible based on an image or texture
Make a Clip Map In the Render tab,
select the T button for Clip Map
Under Layer Type, choose Image Map
Under Projection, choose Cylindrical
Under Image, choose FractalReflections.tga
Make a Clip Map This effect you
can’t see until you render
Press F9 to check it out
Take a Picture for your Homework
Save a JPG of this render to the desktop and call it ClipMap.jpg
Make a Clip Map Change the Texture
Axis to Y and X and render those versions!
Like the displacement map image, these will not change over time
Make a Clip Map If you want them
to change over time, use an animated texture like ripples
Render Tab Matte Object
Turns your object into a solid matte color
No shading or highlights to the object One flat color Interesting effect
with a clip matte
Make a Matte Turn off the Clip Map
texture if needed. In the Render tab
select Matte Object Click on the black
square and select a color
Render the frame and check it out
Render Tab Object Dissolve
Turns the whole object to whatever opacity setting you would like Opaque Semitransparent Invisible
Distance Dissolve Makes the object become
completely invisible as it moves away from the camera Kind of like in a fog
Make a Ghost Turn off the Matte
Object In the Object
Dissolve window, drag the arrows until you have a setting @ 50%
Render the frame and check it out
Take a Picture for your Homework
Save a JPG of your render to the desktop and save it as Dissolve.jpg
Using an Envelope Allows you to change
parameters over time Key frames for
parameters, rather than for the object itself
Any time you see an E box, that setting can change over time
Make Dino Vanish Over Time
Set the Object Dissolve to 0%
Next to the Object Dissolve box, click on the E to open the Envelope The Graphic Editor
opens up Looks complicated,
but it’s pretty easy
Make Dino Vanish Over Time
Click on the Key icon just under the chart
At frame 120 click on the line This sets a
keyframe for Dino at 0% No transparency
Make Dino Vanish Over Time
Click another key frame at frame 60
Switch to the Drag icon Now we are going to
change this value
Make Dino Vanish Over Time
Drag this key frame up to 100 % You should see the opacity ramp up from 0%
from frame 0 to 100% at frame 60, then back down to 0% at frame 120. If not, use the drag tool to make these settings
Make Dino Vanish Over Time
Drag the Timeline slider and notice how your object fades out to nothing and then reappears Scary!!
Turning Off Envelopes
Not as easy as Textures Hold the Command key
and then click on the E box
Choose Remove Envelope
You can turn it back on by clicking on the E again if you want
Make Dino Vanish Over Time
Hold down the Command key and click on the envelope box
Choose Remove Envelope
Drag the Dissolve slider back to 0%
Other Render Settings
Unseen by: Makes the object
unaffected or unseen by various effects
Can even be hidden from the camera
Shadows Turn on or off the ability to
cast a shadow or receive a shadow from something else
Edges Tab Polygon Size
Changes how big the polygons APPEAR to the camera Too small or too big =
interesting effect
Edges Highlights different lines
that make up the object
Tinker with Polygon Size
Drag the Polygon Size slider to 50%
Render the frame and check it out Notice that you can
envelope this effect to have the polygons change size over time
Tinker with Polygon Size
Select over 50% and change the size to 1000%
Render the frame and check it out Polygons are too
big making Dino chiseled
Bring the Polys Back to Normal
Drag the Polygon slider to change the size back to 100%
Paint the Edges Check the
Silhouette Edges box
Under Edge Color, choose a color
Render a frame and check it out
Paint the Edges Uncheck Silhouette Select Other Edges Change the Size to
Medium Change the color
