Export an SDL file

How to save a Scene Description Language (SDL) file for editing and rendering.

Select File > Export > SDL. The File Requestor appears.
Type the full path and file name for the SDL file in the File Requestor, or click Show List and select the file using the File Lister. If you select a file using the File Lister, the SDL file overwrites that file.
Click Save SDL.
To cancel the process, press .

Note the following when exporting an SDL file:

Delete all non-referenced shaders before exporting an SDL file, because all shaders, whether they are assigned to surfaces or not, are written out to the SDL file.
When you export an SDL file, each perspective window generates an image (or series of images) when the SDL file is rendered, because each perspective window has an associated camera.
The file name you use for the SDL file is also used within the SDL file to specify the output image file name. For example, if the SDL file is named Planet, then the camera section of the SDL file contains:
```
pix = “pix/Planet”,
```
If there is a second perspective camera named camera2, the SDL file also contains:
```
pix =”pix/Planet_camera2”,
```
If you have more than one perspective window, but only want to render an image (or series of images) from one of them, either edit the SDL file, or pick all objects, lights, and only one camera, and then select File > Export > Active As ,and use that file to export an SDL file from.
By default, comments are not included in the SDL file. If you want comments included, put the following line in your shell before starting Alias:
```
setenv ALIAS_SDL_LONGFORM 1
```
