If you've worked with Grease Pencil before, you know how tricky it can be to draw complex shapes, like adding rounded corners to rectangles, for example. To make this easier, Blender Artist Dantti has released a tool called Grease Pencil Shape Builder.
It lets you create complex shapes quickly and procedurally, with the ability to adjust things like shape, roundness, and more, and see the results instantly. You can also animate these shapes, which can be hard with regular Grease Pencil's interpolation.
Dantti has just updated the Grease Pencil Shape Builder for Blender 4.5. Plus, there's a 11 pages long manual with tips to help you get the most out of the tool.
