This effect can turn a simple, blurry texture into a piece of seemingly hand-drawn art. These controls allow you to strengthen and fade the effect and control how strongly subtle aspects are shaded. Detail lines are derived from edge detection of the rendered scene. It's fast - the speed cost on top of the existing render pipeline is minimal. It's essentially a post-process effect that analyzes various buffers from the render pipeline and redraws them in realtime. This is the Advanced Cel Shader Pack - a post-process asset that can be added to any game to provide detailed and gorgeous cel shading.
