---------------------------- Deriving Section --------------------------

There's nothing to really derive here, unless you want to alter the animation timings or add sound effects. You can find out more about Deriving on the IMVU's Education Center.

To add sound, I highly recommend you download and use Audacity. It's a free sound editing tool that can export out OGG sound files. OGG sound files compress down to less then 1/10th the file size of WAV files. SO USE OGG FILES!!! You can download it here:

Also avoid looping sounds, as they tend to get annoying to listen to very quickly. Try to keep your volume levels low as well, as IMVU tends to over-amplify all audio playback to near ear-bleeding levels.
