the tutorial for my previous videos about the kuwahara filter.
The next part of this tutorial, making it directional, can be found here: https://youtu.be/JJZBd7Zu0Ug
The sceneUV node needs to have it's code set to "return GetDefaultSceneTextureUV(Parameters, 14);" in later Unreal versions!
More information on the kuwahara filter can be found here https://en.wikipedia.org/wiki/Kuwahara_filter
and more information on using custom nodes in UE4 can be found here https://docs.unrealengine.com/en-US/RenderingAndGraphics/Materials/ExpressionReference/Custom/index.html
The files are available on Gumroad here https://matthijsv.gumroad.com/l/VGNLO
I'd strongly recommend following along with the tutorial, rather than buying the files.
