with VNS 2 Part 2D.
90. We're done with the project
and ready to render. We'll create two Render Jobs. The
MainTest Render Job will be a fast rendering version to
check for mistakes. The MainFinal Render Job will be the
final frame sequence.
91. Go to the Render Task
Mode. Right-click the Render Jobs category and Add
Component of this type.
92. Name the job MainFinal.
This Render Job will use the Main camera and new Render
Options, so select New Render Options. Edit
to open the Render
93. Name the options MainFinal
to match the Render Job. The Pixel Aspect is 0.9, which is appropriate
for NTSC M-JPEG tape output. Images viewed on a computer have
square pixels, so change the Pixel Aspect to 1.
To render the entire animation, change the End Time to
94. Go to the File Output
page and Add Output Event. I'll use QuickTimePro to assemble
the animation and it doesn't read IFFs. Change the Format
to Targa this time. AVI and QuickTime output does not
require frame assembly after rendering, but these formats have
several limitations. AVIs and MOVs cannot be rendered across
a several machines and may lose all rendered output if the computer
crashes before the Render Job is complete. These formats are
best used for tests, as we will set up shortly. Enter MainFinal
as the Image File name and the job is ready for rendering.
95. Select the MainFinal
Render Job in the Scene-At-A-Glance and clone it.
96. Name the job MainTest.
97. Expand the Render Options
and clone MainFinal.
98. Name the clone MainTest.
To reduce the frame size, select Scale and enter h
for half size. Reduce the Frame Rate to 6 frames
99. On the File Output
page, change the Format to QuickTimeMOV. Rename
the Image File MainTest.
100. Go to the Scene-At-A-Glance and click and drag the MainTest
Render Options to the MainTest Render Job. Confirm the
101. We're ready to render the
test animation, so open Render Control.
We don't need the Island or No Tower Render Jobs
so disable them .
102. We'll render the MainTest
Render Job only first time around, so select MainFinal
and disable it. Double-check the settings under Selected
Job and Go to start rendering.
103. VNS warns us that the Terrain
Parameters are currently set to render using Variable Fractal
Depth, which is the default method and appropriate for rendering
single images. It is not appropriate for terrain animation, which
we'll talk about in the next tutorial. For now, take my word
for it and select Depth Maps.
104. Answer Yes to generate
Fractal Depth Maps.
105. Start with frame 0.
106. End with frame 600.
107. Generate maps every 5
frames. In a nutshell, VNS will go through the animation and
keep track of which terrain polygons pass near the camera and
which ones stay distant. The rendering engine will use the resulting
map to subdivide terrain polygons, which optimizes rendering
time and terrain detail.
108. We're rendering to a movie
format, so QuickTime wants to know what codec to use. Let's go
with Animation, Thousands of Colors, Best
Quality, 6 frames per second, and a keyframe every 6
109. The MainTest.mov
animation can be found in the animation folder on the
110. Everything looks good in
the test animation, so it's back to Render Control for MainFinal rendering. Disable
the MainTest Render Job and enable MainFinal. Make
a last check of the render settings and start rendering. This
will take many hours, so take the rest of the day off and we'll
check back tomorrow.
111. It took more than 10 hours
to render the 600 frames. The assembled MainFinal.mov
can be found in the animation folder on the Tutorial 1 CD.
