UE4 Character Cel Shading pack is a customizable material asset pack to help UE4 users easily make quality cartoon character outlook as in Naruto Ultimate and Guilty Gear Xrd. The pack can be found here: https://www.unrealengine.com/marketplace/character-cel-shading-pack.

 

 

The cel shading materials are designed as surface materials so that they can be independently applied to different objects. By doing so, users can freely mix different styles in a scene. For example, as in many Japanese animations, while cel shading is applied on characters, other objects such as buildings, trees, hairs, and weapons may have different (usually more realistic) rendering styles. We believe this kind of style-mixing might be hardly achieved by post-processing approaches like the UE4’s official cartoon tutorial. To provide easy control of wide variety cartoon appearance, our materials support interactive controls of border location between bright/dark cels, cel brightness, smoothness of cel boundary, line thickness/threshold/color, etc. The materials also support many standard maps including normal, specular, gloss, and AO maps.

Our line drawing material is designed to better detect important lines by using more information than depth discontinuity. It also automatically controls the lines to better preserve character appearance when depth changes.

The Mixamo characters in our demo video are not included in the pack. Instead, a detailed document about the scene reproduction and pre-setup level with dummy characters are included in the pack for easy and precise reproduction.

 Version History

— V1.1.0, August 9, 2016 —
Two line-drawing-related options were added: a) Use Normal Map for Line Detection, b) Use Depth Adaptation.
A document “ControllingLines.pdf” has been added, which explains the line PP material principles and parameters.
The document also explains the above newly added options. It also has Japanese and Korean versions.

* Added “Use Normal Map for Line Detection” switch in cel shading materials.
* Added “Use Depth Adaptation” switch in PP line material.
* Added ControllingLines.pdf
