(In a similar way, if you assign an AVI file or MOV file as a bitmap, rendering steps through each frame of the animation.) For example, if you assign a 10-frame animation of a blinking red "Danger" sign to a material's diffuse component, apply the material to a cube, and then render a 30-frame animation, the cube displays the blinking red Danger animation three times. The .ifl file lists the bitmap files to be used with each frame. You can append an optional numeric argument to each file name to specify the number of frames of rendered animation on which it is used. For example: The IFL file listed above specifies sand.tga to be used for the first 20 frames, pebble.tga to be used for the next 40 frames, stone.tif to be used for 20 frames, and boulder.tif to be used for 20 frames. TIP Specify only the file names in your IFL files. The file paths can be derived from the map paths established in your preferences. See External Path Configuration on page 7735. IFL files with path names can be used only on the system on which you create them.

Either use the IFL Manager Utility on page 7344, or use the Sequence check box in a file selector dialog, as described in the following procedures. Notes ■ If the IFL generator has a name conflict with an existing IFL file, it will increment the new file's name to avoid overwriting the existing file. ■ If the IFL generator has any problems with write access while trying to create the IFL file, the process will fail and the IFL file won't be created. 7340 | Chapter 23 Managing Scenes and Projects
