Modeling
Make a plane in Modeler. It will be best
if you create it in the bottom left viewport,
but before you start, change the view from
Back to Front (the little button in the top
left-hand corner of the viewport window).
This will give you a plane that's oriented
correctly when you send it to Layout. It
can be any size you like, but better you
keep to the same proportions as the image
you have. Like I said, if you count the number
of pixels for the height and width of the
image, and then make a box that has the same
dimensions in meters or any other units you
like, you can be sure that when you map your
image onto the plane, it will be the correct
proportions. When you are making the plane,
hit the 'n' key on your keyboard to bring
up a numeric panel in which you can put the
numbers you need.
Once you have made your plane, hit space
to freeze it. Make sure you are in polygon
mode by hitting space repeatedly until you
can see the Polygons button light up at the
bottom of the Modeler screen. Now it's time
to give it a surface. Hit 'q' to bring up
the surface panel. If it doesn't appear,
make sure you don't have Caps Lock on LightWave
is case sensitive. In the surface panel,
give your object a name, I suggest "imageplane".
This isn't really important if all you are
ever going to do is have the one object in
the scene, but when your scenes become more
complicated with more than one object it's
vital.
- Okay, we are done in Modeler. Save your
object and then hit the button in the top right
corner of the screen that looks like a downward
pointing arrow. This will give you the option
to Send your object to Layout. Do so.
Layout
Now we move to Layout. The plane should
be facing the camera. Switch to the camera
view, by going to the button that currently
says "Perspective" at the top left
hand corner of the viewport and changing
it to camera. The plane should nearly fill
the viewport and be square on to the camera.
Now is when we put an image onto the plane.
Go to the Surface Editor and the first texture
setting will be Color. There's a T to the
right of it.
Hit that and you will be brought into a
new window. There's a section labeled Image
with a button saying (none).
- If you click on that button you will see
that you can load an image. Do so. If you move
the surface editor window over a bit, you should
be able to see your plane in the viewport update
with an image, but it might be squished or
look completely unrecognizable. There are two
things to mess around with. Check the axis
for the image there are buttons for X, Y and
Z and also hit the "Automatic Size" button
to stretch the image to fit your plane.
Animation
Okay, we have our plane, we have an image
mapped onto it. Now we need to move the camera
around. Make sure that the camera button
is highlighted at the bottom of the screen
and now when you move the mouse with the
Left mouse button held down, you will see
the plane apparently move (you're moving
the camera rather than the plane, so the
directions will seem reversed. If you'd rather
move the plane, you can still do exactly
the same). Left and Right will move right
and left and up and down will dolly in and
out of the image. Holding down the right
mouse button will allow you to move the camera
up and down at the same distance from the
plane.
At the moment, you are at frame 0 of your
animation. We've already established that
we are working at 25 fps and the little text
box to the right of the slider can be set
at anything you like to give you more or
fewer frames of animation.
Set the camera where you'd like it to start
the animation and hit return twice. This
will set a key frame for the camera. Then
move the slider along a bit, and move the
camera again and set another keyframe. Do
this until you have the motion you want over
the period you want it.
The motion will be choppy because of the
fact that there's no ease-in or ease-out.
You can change this by opening the graph
editor. Be aware that most of the windows
don't block LightWave, so you can have them
open and continue playing your animation
in the background so you can interactively
see what difference your changes make. In
the graph window, selecting a keyframe will
then allow you to change its TCB spline (TCB
stands for Tension, Continuity and Bias)
to give you a better motion. It's easier
for you to play with the settings rather
than me to go into a long-winded explanation…Remember
also that you can change more than one channel
at a time by selecting more than one from
the list at the top left of the graph window.
- Once the motion is as you like it, you'll
want to save it out. You can save individual
frames, if you want to bring them into Premiere,
say, for further post processing, or as an
animation, or even both at the same time. You
do this by choosing Rendering Options from
the Rendering menu up at top left of the screen.
Other things
You can turn on a field chart or safe area
overlay by using the Display Options window
(hit d on the keyboard). These won't appear
in your render and also only appear in the
camera view.
You can change the aperture focal length
and various other settings of the camera
by making sure you are in camera mode and
hitting the properties button next to the
camera button.
- There is a facility to truly emulate different
types of film very precisely with LightWave
so that you can match the other film used in
the production. Using the Virtual Darkroom
plug-in you can set options like granularity
of your 'film' and the way it reacts to light.
It's complicated to use, so don't even ask
me! But there are numerous presets included
for different types of film.
