@winsonzhong - yes. I'll quote my recent response from a previous page of this thread:
The free-form deformation will come post 1.0. I don't want to give an ETA since we're going to continue to polish 1.0 until it's perfect. Then we will take our time to make free form deformation absolutely perfect, though of course there will be beta versions along the way for Pro users.
Once deformation is a little further along and useable in Spriter in a more final form, I'll start adding it to the C2 plugin. It will most likely be webGL only, as html5 has no reasonable way to do this with useable performance, that I've been able to find.
The most recent pro features that aren't yet in the the plugin (sub-entities, variables, tags, and events) will be coming to the C2 plugin much sooner.
