What's New in v1.6 ?

• Version 1.6 features a fully overhauled display system for greater speed, quality and flexibility.
• Many painting and alpha channel tools have been greatly sped up and improved.

• New animated brushes let you paint with a sequence of image and are created on the fly as opposed to being a ‘canned’ effect.  They can be scaled, rotated, flipped and keyed, and can make use of brush dynamics just like regular custom brushes. [show me more]

• Onionskin lets you see though your paper like traditional onionskin used in animation studios.  You can see-through the two prior and two following frames as you paint the current frame. Use it with the already powerful painting system to create original cel animations. [show me more]
