Have any of you gone through the process of animating vector art (Illustrator) for Unity?
My team is using Unity 4.5 and we basically can't use plugins/extensions (weird educational reasons). So, my current method is sprite sheets: by hand, I'm arranging my vector art into a grid formation in Illustrator, hand-editing each "frame" of the grid, then exporting the image as a sprite sheet into Unity.
I really wish I could just move anchor points around, on a timeline. Please oh please tell me the easy solution I'm missing
For Nefarious, we're using TK2D for sprite sheets in Unity, but animating everything in Flash. I'm exporting as video and using QuickTime to export as a series of images (exporting as images from Flash doesn't animate nested MovieClips). The workflow is a bit of a pain over just running the game in Flash, but I'm primarily a Flash developer so I have a very basic swf that runs the animations immediately.
I'd definitely recommend Flash over Illustrator, though the line work's not going to be as smooth. If you really want to be fancy you can try Toon Boon, but I haven't been able to wrap my head around the interface yet.
