Cell Shading shaders by Crescent
First off I want to say that I am not trying to advertise pwToon at all. I recently bought it and like it a lot, but mostly I am just pointing out a cool little freebie shader kit for it that I found. There is a shader pack by Crescent that gives pwToon a Cell Shading effect, and while I haven't mastered it yet, it's certainly nice! The readme that comes with it says that it is a freebie, redistributable and even allowed to be edited!
Below are links to the file, a guide on deviant art, and a render. The Shaders are by Crescent, the guide is by CyonixGFX on Deviant Art, and the render was done by myself.
Render (Thin Cell Shading):
Please do read the guide, it is extremely well made and informative. Hope you all enjoy it like I do! The guide is 2 years old, but still works witth DS4.5
Edit: The render is using Hitomi for Genesis (If you happened to read by post about trying to figure out what figure to buy, I chose her xD) and was done extremely quickly, so excuse the lack of detail.
