1. Uncheck "Fixed Height Above Surface"
In the horizontal plane, the "z" value will be the same as the
camera automatically (unless you override the value). However,
we are also going to be taking pictures of the UP (and possibly
DOWN) directions relative to the camera position so we don't want
the target fixed.
2. Set cloud/sunlight parameters
3. To the left side of the Rendering Control window there is a
scroll bar next to the word "Detail". Set Detail to Maximum (far
right). Also, click on the SETTINGS button to view the RENDER
SETTINGS window. In the QUALITY section, scroll "Atmosphere" and
"Cloud shading" to high accuracy. In the OPTIONS section uncheck
the "Render Lanscape" option.
4. Below the SETTINGS button is a section to control the IMAGE SIZE.
Set the Image Size width and height to the maximum 512x512 pixels
for the best results. If you want to go lower in size, the images
must be square and in powers of two (i.e., 128x128, 256x256). You
will of course have less detail as well by going lower in size.
5. Make sure the folder listed in the function below exists
initanim "C:\C4\Import\tga\skybox\skyRender", 1

InitAnim BaseImageFileName,StartFrameNumber
The InitAnim command tells Terragen that an animation is to be
rendered, and initialises the appropriate variables. It is
necessary to have this command before any calls to FRend.
We don't want clouds moving for skybox renderings, but I've put
the comments below for information--CloudVel is used to automatically scroll the clouds across the
sky. It will position the clouds correctly for each frame, no
matter what frame number the script starts at. CloudPos tells
Terragen where the clouds would be if it were rendering frame 0.
