I'm launching a site for free shader assets (CC0-licensed) for use in multiple engines: currently Unity, Godot, and Unreal Engine, with more effects and platforms planned in the future. cc0shaders.com

I was inspired by sites like @ambientcg.com where you can find CC0 textures, although it's tricky to do the same for shaders since each engine tends to use a custom format for shaders (node-based vs code-based, special wrapper languages, HLSL vs GLSL, weird custom uniforms and input data).

I made a Godot shader tutorial about the depth and stencil buffers! They greatly expand the kinds of effect you can create, ranging from x-ray vision and silhouettes, to more effective water shaders, to 'impossible' rooms where you can only see one set of objects from each side.

Transparent objects work differently to opaque ones. We sort the back-to-front to ensure the correct result, and blend the color of the object with the existing screen contents based on its alpha, the fourth color component (after RGB). Learn how it works in Godot: www.youtube.com/watch?v=2rw5...

Textures can be used to vastly increase the amount of texture detail on the surface of an object. Learn all about texture coordinates (UVs) and how to manipulate them in this tutorial: www.youtube.com/watch?v=ktWH...

I've been working on a Godot shader tutorial series for a little while now and I'm happy to finally release the first part today! It covers the absolute basics: vertex and fragment shaders, rasterization, parameters, and shader hints. www.youtube.com/watch?v=ZJv3...

I modelled the series on my previous work with Unity, so the next parts of the series will cover textures, transparency, depth, lighting, PBR, alpha clipping, and more. It won't be 1:1 with the Unity series, but it'll cover similar concepts. danielilett.com/2026-10-01-g...

Retro Shaders Pro is currently on a flash sale for 70% off for just one day! Just in time for the latest update, which adds support for normal mapping and Unity 6.4 compatibility. assetstore.unity.com/packages/vfx...

Recently I decided to retire one of my old asset packs and make it free, so I wrote about how I made a two-pass Gaussian blur with sparse kernel support for the asset: danielilett.com/2026-04-22-a...

I released this asset pack under the MIT license over on GitHub: github.com/daniel-ilett... That said, it's still on the Asset Store too for free - I'm just not planning to continue support beyond Unity 6.3: assetstore.unity.com/packages/vfx...

By adding a step size parameter, you can skip over some pixels in your blur kernel. I can use a 100 x 100 kernel so I still read far-away pixels, but I can skip over every second pixel to save computational power with minimal reduction in quality. Right half uses sparse kernel.

The gist is essentially, the blurring process is separable, so we can blur an image horizontally, then again vertically, and it's identical to doing a 2D blur in one pass, but it's significantly faster, turning a O(n²) process into O(n).

This only took five months to make, but my tutorial about lighting in Unity shader code just dropped! Learn all about realtime directional and point lights, diffuse, specular, ambient, and Fresnel lights, shadow mapping, and more! www.youtube.com/watch?v=bH--...

You can get all of my asset packs for an absolute steal - just $25 - for the next few days over on the Asset Store! It's got holograms, PSX shaders, layer-masked post processing effects, toon cel-shading, and much more! assetstore.unity.com/packages/vfx...

And lastly, Shader Toolbox is a collection of handy shaders with full PBR map support (where applicable) and a library of shader subgraphs you can use in your own effects! Plus, a _CameraTransparentTexture so you can see transparent objects in some of your effects.

Hologram Shaders Pro is a collection of stylised sci-fi effects which support vertex-based and slice glitches, scanlines, random noise grain, Fresnel highlights, dot matrix patterns, and gridlines.

Retro Shaders Pro is a bundle of powerful PSX and N64 shaders with a CRT/VHS post process effect. It supports affine texture warping, vertex snapping, texel lighting, cubemaps, dithering, console color filters and more, and I wrote about it here: danielilett.com/2026-01-27-a...

I just released my second Godot asset pack: Hologram Shaders Pro for Godot! Apply dynamic glitches, scrolling scanlines, procedural noise, gridlines, and dot matrix patterns to any mesh and instantly make it feel more futuristic!

Three of my asset packs are 50% off on Fab right now! If you need PSX shaders, holograms, or layer-maskable post processing effects for Unity, then it's the perfect sale for you!

For my Retro Shaders pack for Unity, you can now emulate the colour palettes of older consoles/computers! Here's a few of them.

Some of them are just rough approximations, and most don't implement the cap on the number of simultaneous colours, but I've done my best to make the total palette restrictions as close as possible to the original consoles.

Unity is running its New Year Sale right now and THREE of my assets are included! If you like my tutorials and you've been looking for PSX or CRT shaders, post processing effects, or toon cel-shading effects, then check out my asset packs at a 50% discount!

If you're looking for post process effects which you can mask out per-layer, you'll want Snapshot Shaders 2. With realistic effects like blur and height fog, plus stylized painting, pixelation, and synthwave shaders, there's something here for any game: assetstore.unity.com/packages/vfx...
