The Grease Pencil Line Art modifier has just landed in master! The spiritual successor of Yiming Wu's LANPR, the Line Art modifier promises to be groundbreaking for Blender NPR artists wanting to generate accurate line art for their scenes and visualize the result in real-time, all in vanilla Blender.

Initially designed by Yiming Wu as a real-time Freestyle alternative, this latest iteration combines the power of LANPR's original line generation with the versatility of Grease Pencil. As such, the Line Art modifier generates the Grease Pencil lines from the scene and displays them in the viewport in realtime, after which they can still be manipulated and modified using the plethora of GP modifiers and tools available.
