+# Simple Height Fog Effect
+![Unity Version](https://img.shields.io/badge/Unity-6000.0.27%27LTS%2B-blueviolet?logo=unity)

+ 
+A shader effect that simulates height fog on a plane mesh. It was created for Serious Point Games as part of my studies in shader development. It was created for Unity 6 URP (6000.0.27f1) 
+but it can work in other unity versions (like Unity 2022 or Unity 2019) and other pipelines (like Built-In).
+
+
+It comes in two variants, one being a simple height fog (using Unity’s built in particle unlit shader which can be 
+used to re-create a height fog) and a custom two color height fog.
+
+You can refer to the effect's documentation for more info (should be in the repo and its release as a PDF file).
+
+## Features
+- Simulate height fog in areas only covered by the plane mesh, saving resources unlike the post processing approach
+- Can add a noise texture to the fog, using a custom noise texture (2 Color Fog shader)
+- Can also animate the noise texture within the fog (2 Color Fog shader)
+- Customizable fog color & parameters

+What the two color height fog eff ect looks like with the eff ect on, the red and off -white color is just used for demonstration purposes only to make the fog more apparent.
+
+## Installation
+1. Clone repo or download the folder and load it into an unity project.
+2. Drag the material onto a plane gameobject/mesh that you want to apply the eff ect on, or go to the object’s inspector panel and change its material to the material with the 2 color height fog shader.
+3. [Optional] If you want to use the simple fog one like the one I implemented, create a new material, go to Universal Render Pipeline > Particles > Unlit, then enable soft particles and ensure the material’s
+   surface type is on transparent instead of opaque.
+5. Optionally, you can use one of the prefabs by clicking and dragging one of the prefabs into the scene.
+  a. You can scale the plane to make the height fog area bigger or smaller.

+## Credits/Assets used
+Some parts of the code is adapted from Unity Technologies's Particles Unlit code, which is found from https://github.com/Unity-Technologies/Graphics/blob/master/Packages/com.unity.render-pipelines.universal/ShaderLibrary/Particles.hlsl
+or in here, https://github.com/Unity-Technologies/Graphics/tree/master/Packages/com.unity.render-pipelines.universal within Shader or ShaderLibrary folder
+
+Some of the code is adapted from my other effects, like the Volumetric Spotlight Shader Graph and Gradient Fog Effect.
+
+The method used to create the simple height fog eff ect is from this Youtube video by Vanmillion Studios, https://www.youtube.com/watch?v=-s7_l3TXWPM.
