This is a collection of rather funky (and useful) shaders for visual effects in Unity. You can access the shaders in Assets/shaders/shaders/ and the materials used in the scenes from Assets/shaders/materials. The shaders are created for URP & HDRP with ShaderGraph. However I am considering creating some CG variants for non-SRP builds.
I frequently create a bunch of shaders for VFX in Unity, and I'm sick of copying them from project-to-project. So this repository serves as a public index of reuseable shaders. It also serves the purpose of showing newcomers to shader development some interesting examples.
In the current version, there are a total of 3 shaders. Note that the path mentioned below is relative to assets/shaders/. For example, the full working path of the billow shader is assets/shaders/shaders/billow.
| Name | File | Description | Applications |
|---|---|---|---|
| Billow | shaders/billow |
A world-space billowing displacement shader, using Perlin noise. | Rolling clouds, Blobby objects like slime |
| Pulsate | shaders/pulsate |
A sinusoidal pulsating shader which inflates an object via normal displacement and flashes a given colour. | Hit / alert markers on NPCs or objects, things which are about to explode |
| Snow | shaders/snow |
A procedural snow shader which works by comparing dot(u, n) where u = vec3(0, 1, 0) and n is the world-space normal. Performs displacement, albedo and emission calculations. |
Snow, Slime |
| Distance-based | shaders/distance-based |
A distance-based shader, which applies 1 or 2 subgraphs depending on a given distance to world-pos vec3. |
Expanding "shockwave" effects, Distanced-based Dissolve |
A pulsating shader which flashes and displaces over time. Perfect for bombs which are about to explode, or hitmarkers for NPCs.
A cloudy, billowing shader using world-space gradient noise. Very good for rolling clouds and small low-poly puffs of smoke (e.g. when something's hit, or explosions).
A shader which adds snow procedurally using a bit of cool vector math. Good for adding snow or coating objects with a thick viscous layer of something (like slime or acid!).
A shader which applies 1 of 2 effects, given the distance to a specific world position (passed as a uniform). In this example, the first effect is render with a normal colour (the red portion) and the second effect is to not render at all (alpha = 0). Based on the distance, the given effect is chosen. To edit the two effects, see the two subgraphs in the folder for this shader.
