Hi Nicholas,
ProAnimator and Invigorator can both read the same object file formats, including .zxo, the native Zaxwerks format. This format allows you to share fully-constructed objects, with materials applied. If you have access to Invigorator, you could export the objects in your scene in the .zxo format, then import those objects into a new ProAnimator scene, to save some time building the elements.
Because ProAnimator and Invigorator handle motion in completely different ways, you can’t just replace the Invigorator effect applied to a layer with a ProAnimator effect.
Does this help?
