The next part shouldn't take as long, and it'll be all about Physically Based Rendering. Lighting is such a gargantuan topic so maybe I'll also squeeze in a couple of installments about baked lighting and non-photorealistic lighting like toon shading after that.
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--...
I've finally finished the next installment of the Unity shader code series! It's all about lighting: realtime main and additional lights, shadow casting, and normal mapping. It'll go live on Monday!
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.
Toon Shaders Pro focuses on flexible cel-shading effects with support for two diffuse cutoffs, specular and Fresnel lighting control, metallic objects, and a customizable outline shader with multiple drawing algorithms.
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.
Snapshot Shaders 2 comes with dozens of post process effects, including height fog, synthwave, Gaussian blur, oil painting, silhouette, underwater, glitch, and colorblindness filters. Every effect can be masked to specific Unity layers!
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...
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...
I made it with Godot 4.5 so it should work with any version from that point onward: danielilett.itch.io/hologram-sha...
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!
P.S. did you know they sell Unity assets on Fab? I didn't, I assumed it was just Unreal stuff.

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!
I wrote a lil' devlog style thing about Retro Shaders Pro, talking about the PS1's visual limitations and how I chose to recreate them! It's nice to get some of my thoughts out onto (digital) paper. danielilett.com/2026-01-27-a...
If you like the look of these filters, then check out more of the features in this lil video: www.youtube.com/watch?v=Li_z...
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.
For my Retro Shaders pack for Unity, you can now emulate the colour palettes of older consoles/computers! Here's a few of them.
And for those making cel-shaded games, don't miss out on Toon Shaders Pro! It comes with a flexible toon shader with control over diffuse and specular lighting, plus a powerful outline shader with a ton of usage options. assetstore.unity.com/packages/vfx...
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...
Retro Shaders Pro is a collection of PSX, N64, CRT, and VHS shaders, with affine texture warping, wobbly vertex snapping, texel-aligned shadows, and fuzzy VHS visual artifacts. Relive gaming's golden age with these shaders: assetstore.unity.com/packages/vfx...
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!
I'm finally branching out into Godot shaders a little more, starting with a port of my Retro Shaders Pro pack, which brings PSX, N64, CRT, and VHS effects to any game you want to make! danielilett.itch.io/retro-shader...
Learn all about vertex and tessellation shaders and create a wave shader in this latest installment of my Unity shader code series! With tessellation, you can increase the number of vertices on the fly, making vertex displacement effects look nicer! www.youtube.com/watch?v=Surw...
With the depth buffer, Unity is able to draw things in the correct order. We can use depth in shaders to create many effects, including silhouettes and x-ray vision! Learn all about it in my tutorial: www.youtube.com/watch?v=2wa6...
Learn all about transparency in code-based shaders in the third part of my Unity beginner series! With transparent objects, you need to sort objects back-to-front and blend their colors with the existing screen contents using an alpha value. www.youtube.com/watch?v=lmgY...
I've been catching up on written versions of my shader tutorials on my website and I'm finally up to date, starting with my recreation of the Recall rune from Tears of the Kingdom here: danielilett.com/2025-10-11-t...
I just released Part 2 of my Shader Code Basics series, which is all about texturing and UV coordinates! Textures give you a ton of control, so they're a fundamental building block for most of the shaders you'll write. www.youtube.com/watch?v=XwHp...
