This is indeed the model that LiveMotion uses for animation. It, like

AfterEffects, can animate every attribute of every object over time

including swapping out the contents of an object (such as a shape,

photograph, text, etc.) This allows multiple effects with one basic object

rather than the layer model used by Photoshop and ImageReady.

Well, we bypass the manual process of symbol creation into an automated one.

Instead of Symbols and Instances, we make the application manage these.

"Aliases" are true clones of each other and are identical. (Edit any single

object in an alias group and the others change as well.) Editing takes place

in the main layout window. Aliases can, of course, be disconnected.

Just polishing things as we go. Let me know if you have any questions about

LiveMotion John. I'd love to answer them for you.

Amen!
