Note: Grease Pencil is on a very early stage of development. Start by adding a Grease Pencil object and play with the brushes, tools, palettes, and don't forget to check out the new modifiers. It's all work in progress but quite fun to play with.
Just like in 2.7x, there is no specific workspace/layout for 2D animation yet. The tools are there you just need to dig through the panels. We are working on it to make 2D animation as accessible as possible. Feedback is welcome! Which tools do you use the most?
But a build is nothing without something to play with! Download and get your hands dirty with two early sneak-peek samples files from Hero. Animated by Javier Salvador and Sergi Miranda.
