It might be useful that iClone Pipeline have a bridge to allow any scene loaded in Cartoon animator show in iClone's scene view with access to edit the 2D animation and be timeline.

It would have the option to show in the background or as an overlay over the iclone stage so that the 2D parallax can work or load the 3D view of Cartoon Animator into iClone

This could allow more expansion to visual FX but not only that, 2D Characters & props along with iClone characters & props would be in sync and offer a non destructive workflow. iClone could be used as a reference for physics & animations tracing for 2D Characters AND vice versa!

It seems likely that Cartoon Animator Pipeline should have iClone's stage show within Cartoon Animator's stage as well but at this time I can't foresee any reason why it makes sense other than a familiar UI and extra features for the 2D animators.

The Bridge is a bridge to fill the Gap of workflows between programs to make what was impossible, possible.
