After many months, Blue Pencil has been released and is available now.
Blue Pencil is a Maya plug-in that allows 2d drawing directly on the viewport. It is a multi-purpose tool that can be used as a grease pencil for planning, annotation and illustration. Animators can use if for thumbnailing, rough blocking and arc tracking directly in Maya. Additionally, it may be used for shot reviews, video tutorials and screencasting.
Quickly override the display color of one or more selected objects using a color index UI. With this script it is no longer necessary to dig deep into the Maya's Attribute Editor to enable drawing overrides and set the color using a slider.
Blue Pencil has finally entered the closed beta testing phase. The beta testing group consists of a small, but diverse, group of individuals ranging from students to industry professionals.
Blue Pencil is tentatively scheduled for release in June. Additional details will be posted as they become available.
