As is right now, you have to jump through a real learning curve to get your custom drawn vector characters into CTA Pro..
You should really consider a template import method for people to bring in their own work to use with your App. A template would be a blank character type and we just drag our Arms, face, eyes, etc... to the character body template and then adjust on screen so that the character fits correctly with the bone map = and whammo... done.
or a least give information where and what file format the vector characters are now, so we can open our graphics app and change them ourselves.
Love the software, but am a bit peeved about the lack of ease for using our own art. Seems that what EVERYONE will want to do.
