This is a refraction/glass shader created with Amplify Shader Editor. The shader uses a better refraction model resulting in more realistic refraction compared to other shaders. This shader features 3 different refraction modes depending on your use case, the ability to blur the refraction, rain droplets, emission scrolling/fresnel, and iridescence. There are other smaller features included with the shader as well. There are also four example models included using the shader and showing off some of the different features the shader provides.
