This is the first major overhaul of the Advanced Cel Shader since its release in 2014 and represents a re-imagining of how cel-shading in games can be done. Redundant features have been removed and the shader has been refocused on core cel-shading functionality. This is the only cel-shader for Unreal Engine that provides results this clean.
Version 2.0 also includes functionality not seen in any other game engine post-process cel-shader:
Exclude items from shading
Exclude items from outlining
Invert outlining behaviour
The cel lighting model has also been re-done and is now faster, supports hundreds of simultaneous realtime lights, has easier implementation and provides more reliable results.
