NPR Face Shader

A Blender addon to easily build custom smooth lighting for use on NPR faces using grease pencil.

Features:

• One-click solution for horizontal lighting on NPR characters (potential substitute for normal editing)
• Utilizes user-drawn grease pencil lines to place shadows in flexible locations
• Automatic material and node group creation for shadow texturing
• Easy driver initialization for response to sun/head rotation

Note: As of now, this style of face shading only works for horizontal lighting shifts. It can be modified to work for vertical lighting, but you still can't readily blend between both. I am working to see if I can come up with a solution for this and will update this addon with any progress. For now, it at least supports the most common use case.
