Standard Pipeline Only! Not compatible with URP!

New URP RefractiveShader asset -> https://assetstore.unity.com/packages/slug/315202

This shader emulates light refraction as it passes through media with different refractive indices.

However the effect is purely artistic/cosmetic as the method of distortion is not based on physical model of refraction.

Update 1.3 - Added new Lit and Unlit shader with:

- Masking parameters for refraction

- Alpha blending

- Sample count based quality tuning

- More Physically correct looking distortion

Update 1.2

- Added unlit distortion shader

- Added a simple particle distortion shader

Update 1.1

- Depth masking (objects in front do not get distorted contours)

- Color alpha controls transparency

- Added Factors to fade Texture maps

- Added Emissive properties

Features:

- Built on Unity's Standard Surface shader

- Chromatic Abbreviation (CA)

- Normal Map affects Distortion

- Smoothness < 1 Blurs refracted scene

Includes:

- 3 Shaders with different GPU footprints

- Demo Scene with some textures
