In this video we demonstrate an easy method for creating whiteboard animations in Blender with the help of the grease pencil tool.
-Draw lines with grease pencil
-Turn lines into curves
-Add the build modifier to the curves and set the start frame and duration to suite your timing
-In the curve settings, set the fill mode to “full”
-Add some bevel to the curves to make them thicker and visible in renders
-Add a shadeless material to the curves with the color of your choice
-Render the animation
