This will give you a B&W image of the terrain map and will allow you to "paint" higher or lower much like painting displacement maps in Source Engine Hammer.Ģ) When satisfied with your painting, click render preview or the 3D button to preview how it looks. Now start preparing for final render by first sliding the detail slider to the right, then setting the render settings image size to 512X512. Position your camera in the final place via the mini map or 3D button. Change the altitude of the camera by changing the "Z" meters (i have set to 500 for this one, but for most skyboxes id suggest a lower altitude). Create a folder on your C drive and name it terragen. Go to Exectute script in the Terragen menu. This script has the output directory set to the terragen folder on C. You can edit the script with notepad to change the output directory and name.ģ) Terragen will now render out 6 images. When done they will be BMPs called "mysky"in the directory as the goldsrcskybox.tgs script specified.
