Refraction shader for Unity's URP (Universal Render Pipeline).
Based on HDRP's ScreenSpaceRefraction.
This shader is created in Shader Graph, so you can easily modify it to add more features. (ex. NormalMap)
Please read the Documentation and Requirements before using this repository.
(Sample)
Dithered Transparent Shadows are available in URP 14 (Unity 2022.2) and above. (with high PCF shadow sampling)
