## Overview An ice shader with fake cracks depth and depth texture transparency (you can see outlines of other objects below the ice). ### How does fake depth work? The shader is using a technique called **Parallax Mapping**. Basically, it samples the cracks multiple times. Each sample it slightly changes the UV based on the tangent space's view direction. It gives the illusion of depth. I know it sounds kind of confusing (*because it is!*), so please check the code in *Assets/Shaders/Library/HLSL/Ice Depth.hlsl* or you can read more about Parallax Mapping [here](https://en.wikipedia.org/wiki/Parallax_mapping). ### Notice The more samples the shader does, the slower it runs. So be careful with *Samples* setting, especially on mobile devices. ## Important Notes ### Compatibility The shader is tested only in **Unity 2021** and only with **URP**, so I cannot guarantee it will work properly in earlier versions of Unity or different render pipelines. ### URP Settings Please make sure **Depth Texture** is enabled. Otherwise you will not be able to see objects below the ice. ## Examples ### GIFs   ### Screenshots
