Jiffycrew Post Processs Line. This is not just an outliner.

While outliners only detect outlines of objects, Jiffycrew Post Process Line detects both outlines and rich interior feature lines of objects. To do so, it incorporates an advanced computer graphics feature line extraction technique introduced in the "Suggestive Contours for Conveying Shape" SIGGRAPH paper. The Suggestive Contour is a complex differential geometry mathematical definition to find view-dependent surface inflection points. We believe our Jiffycrew Post Process Line firstly introduces this technique to game industry as an Unreal Engine 4 implementation.

By incorporating this new line definition, this pack enables generating revolutionary line rendering images that provide an illusion of hand-drawing sketches by skilled artists.


Line-Augmented PBR: Rich Lines on top of PBR

Making an unique outlook is one very important aspect for successful game development. Imagine combining this rich line rendering technique with UE4's PBR. We show such rendering examples above. Find how the rich lines provide unique artistic feeling on top of realistic shading.


Redesigned User Experience of Line Application Process

This asset pack provides extremely simplified line application method. Lines are applied by just one drag of JiffycrewLineManager. All the properties that affects to lines are controlled in the added actor.
