Builtin Refractive Shader

Builtin Pipeline Only! Not compatible with URP!

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

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

Effect is purely artistic/cosmetic, the method of distortion is not based on physical model of refraction.

Tested on PC(win, linux) and Android builds

Features:

• Built on Unity's Standard Surface shader
• Chromatic Aberration (CA)
• Normal Map affects Distortion
• Smoothness < 1 Blurs refracted scene
• Other refractive materials visible from behind
• Tunable blurring sample count
• Supports separate Metallic Smoothness textures
• Supports combined Metallic Smoothness (R,A) texture
