In celebration of the holiday season, I am pleased to offer Blue Pencil (http://zurbrigg.com/blue-pencil) for only $49.
This offer is valid until January 3rd, 2013.
Blue Pencil Overview
Blue Pencil is a plug-in for Maya that brings 2D drawing to the 3D viewport.
It is a multi-purpose tool that is useful for, but not limited to:
Grease Pencil - planning, annotation and illustration
Animation - thumbnails, rough blocking and arc tracking
Model layout and topology planning
Shot review tool
Tutorials and screencasting
Blue Pencil provides pressure-sensitive Wacom support for line thickness (pencil tool) and opacity (brush tool) along with an eraser tool and eyedropper. All drawing operations have native undo/redo support and the drawing data is stored directly in the Maya scene file.
From an animation standpoint, keyframes are integrated directly into Maya's timeline (for easy re-timing), keys can be cut, copied and pasted, and the lightbox (onion skinning) can be used to see pre and post keys.
