Terragen classic

Terragen is a scenery generator, created with the goal of generating photorealistic landscape images and animations. It is available for Windows and the Mac OS. Terragen is free for personal, noncommercial use, with only a few limitations.

Terragen Classic is capable of near-photorealistic results for professional landscape visualisation, special effects, art and recreation. Terragen Classic has been used in a variety of commercial applications including film, television and music videos, games and multimedia, books, magazines and print advertisements. For just a small selection of projects Terragen has been used in, please visit the commercial use page.

Despite the fact that Terragen Classic can be used for professional landscape visualisation projects, it is accessible and easy to get started with. You could be rendering your first landscape image in as little as 15 minutes after installation.

Make your scene

There are a great many tutorials on how to create scenes using terragen and the application is relatively simple and encourages exploration.

Having created your terrain this tutorial will describe how to create the images that you'll need to import your landscape into Urban Terror as a skybox.

Making skybox images

Before we proceed you should first confirm that your scene is suitable and your camera is position correctly.

Common mistakes when making skybox images with terragen

• Your camera altitute is too low
• Your camera is inside the ground or a mountain

For these reasons I usually place a camera at 30m above the ground and tend to make only flat landscapes.

Check it will work

With your world ready you should enter the values

0,0,0

For your camera orientation.

Click the render preview button and confirm that your scene renders as you'd expect.

Change the camera orientation to

90,0,0

and once again, render a preview. Check it looks ok.

Repeat for camera orientations values of

180,0,0 and 270,0,0

If all the test renders look good it's time to set up for final renders.

Terragen settings

First of all, in terragen in the rendering control dialog.

Render settings

From the image tab set the image resolution. In terragen classic the maximum resolution is 960, set width and height to this value

Set the quality level to be as high as your computer can handle.

Camera settings

Set the zoom/magnification to 1

Other settings

Feel free to experiment with other settings.

Generate the images

With the camera orientation set to

0,0,0

Click the render image button, this is your front image and should be saved as mysky_ft.bmp

Generate the following images using these camera orientation values

 90,0,0  mysky_lf.bmp
180,0,0  mysky_bk.bmp
270,0,0  mysky_rt.bmp

With the sides completed, we need to generate an image for the up and down faces.

0, 90,0  mysky_up.bmp
0,270,0  mysky_dn.bmp
