Have you seen the color changing face parts, or the non-shrinking parts, and wondered, "How do they do that?" Well, this should clear things up. (Sorry, but I don't have any pictures of it, I can almost never get into the Face Factory.)
To make a color-changing part, start off with the normal part. Then, as it shows you the second frame (of it smaller), change whatever you want about it. Size, shape, color, position . . . it goes on forever. Do the same thing with the other two frames. Make sure to zoom in, or this can be tricky!
For a non-shrinking part, you have to start with the second or third box. Make the part the size you want it to be the whole time. Next, as it gets smaller, remake it, but the same size as the first. Do this with the other two. You will probably want to use the third box, unless it is something smaller.
Well, I hope that clears things up.
This is Pretzeboy, going to go try to make a face part!
Aw man, it's closed again.
