Aquarelle Shader - recreating the Style In Unreal Engine 4 

Introducing Aquarelle Shader , taken from my Stylized Post Process Shader Pack. Aqaurelle is a form of Painting Style resembling WaterColor, with thin and transparent layers. This one was extremely challenging to recreate in Unreal. I tried to add a blend with Gradient based Quantisized WaterColor and PencilSketch, with some Vignette and RandomNoise Layers for Variation.
The video demonstrates Material Instancing and how to tweak the parameters to give a unique look and style for your game, and a small playthrough at the end.
Localized post processing is supported in my pack , which means you can apply the shader either to entire scene, or to certain objects, via custom depth stencil. You can also exclude the background sky atmosphere from the effect of the shader, or apply a different shader to the sky altogether. The below pics shows the Kuwahara filter applied on to the sky. which goes along perfectly with WaterColor , Toon , or Related Stylized Shaders.
