Yes this is very expensive but it's amazing. There are 18 poses (m1 through m18) and 7 facial expressions (f1 through f7).
If you want to make a movie:
Type = *movie #1 #2
Both '#1' and '#2' are time measurements in seconds. #1 is the length of the final movie. #2 is how many seconds it's going to wait before you start recording. So, if you want to make a 20 second movie that starts five seconds after you hit return, you would type *movie 20 5
The video is stored in your IMVU folder. What's more, you can type *YouTube and have your video automatically upload to your YouTube account. AWESOME!
*UPDATE April 15th: the video option is currently not working, i can't control this, this is a problem with the mesh, hopefully it will be fixed soon*.
