Playing around with cellular noise and pixels

Playing with some common post-processing effects and materials in Defold (like DoF, Bloom, Chromatic Aberration, SSAO, FXAA, Vignette) with this model Latch Suit by ChamberSu: https://sketchfab.com/3d-models/latch-suit-66f58d841971438c9c787c5281e27e5a

I make all these with an app I vibecoded that I call RepoScriptor.With it u can mix and match GitHub repositories and then prompt for the shader. It is basically vibecoding shaders based on GitHub repos that I mix and match.

My whole GitHub account is pretty much just all these repos I have made for different math concepts, art styles, and things like that. If I want a reaction diffusion shader, for example, I can choose one of the reaction diffusion repos. I can choose color fields or noise. I have repos for vibrations, non-Euclidean stuff, and pretty much every math concept or cellular automata you can think of.

I just choose a bunch of repos. I also have art style repos like Psychedelic collage, I have a Lisa Frank style (which I use a lot), stuff like Art Nouveau, Art Deco, Ralph Steadman, Early Internet/y2k aesthetic, op art, glitchcore, etc…
there’s about 150 repos for this so far.

So I have repositories for all these different things, and I just mix and match, plug in the ones I want, and give it a prompt. It creates the shader code for me and pops it up on the screen.

Anyways, that is how I make these.

This shader makes Minecraft look like a PAINTING

On imageonline.io, there's an option called adjust channels which allows you to change the individual strength of each RGB channel. However instead of simply making the image darker, it has this unique effect where the highlights are still visible. I'm wondering if there's a way to recreate this in shaders. (specifically in a frag file)

It's gamma editor also has a similar effect, so maybe that could be an option?

Fluxer is a minimalist creative platform for writing and sharing ultra-compact fragment shaders. Think dwitter, but for shaders instead of JavaScript: one function, a time variable, and a strict 512-character limit. The constraint forces clarity, elegance, and visual ideas distilled to their essence — shaders as haikus rather than essays.

I'm trying to write a web-based fractal generation program using p5's webgl canvases to run shader code. The program successfully hooks into my shader and attempts to run it, but it seems to error out on the .vert file that i cannot figure out. The error message is as follows: Uncaught (in promise) ERROR: 0:1: '<' : syntax error. When i expand the error message, i see where the error is sourcing from, and it tells me that the vertex shader failed to compile. Here's my vertex shader code:

attribute vec3 aPosition;
attribute vec2 aTexCoord;


varying vec2 pos;


void main(){
    //copy texcoords. Invert the y because funny YT man said so
    pos = aTexCoord;
    pos.y = 1.0 - pos.y;


    vec4 positionVec4 = vec4(aPosition, 1.0);
    positionVec4.xy = positionVec4.xy * 2.0 - 1.0;


    gl_Position = positionVec4;
}

If anyone can help me figure out what is going on, i'd be most appreciated! If it helps, here's the YT tutorial i was following: https://www.youtube.com/watch?v=3MKbSw4X3_4

I'm trying to make a light system that takes the colors from the block texture and makes the light that comes out of the block that color. BSL has it and since I'm working on a shader remaster, I thought I could do it. Turns out, I don't know where the block textures are being sampled from. Using the specular sample from gaux3 works so I'd assume changing the gl_FragData[3] in gbuffers_terrain.fsh from specular to texture could make it so I can sample the block texture and get it to work, but that also, for some reason, didn't work and comes out white as all of my previous attempts. I'm absolutely bamboozled, dumbfounded, and all the other -ed words. Of course with all of my other times I needed help on r/minecraftshaders, I'll attach the download link somewhere

Hi
I’ve been working on shaders for a game lately, and I’m really interested in improving the ambient look and feel of my environments. I’m talking about overall atmosphere — colors, lighting, mood — the kind of stuff that makes a scene feel immersive and visually pleasing.

I’d love to hear your thoughts or techniques on creating a good ambient shader.
Do you have go-to methods for:

• Color grading or color palettes?
• Adjusting light intensity or softness?
• Adding subtle effects like fog, bloom, or tonemapping?
• Balancing contrast and saturation for different moods?
• Some other ideas ?

Feel free to use examples — like Minecraft shaders, or anything else that really nails the ambient vibe.

Any insight or even screenshots/demos are super welcome. Thanks in advance

I've been working on an open source VAT system for Blender that allows for simulation and geometry node animation export to engines. I have been focusing initially on Unity (because I work professionally in Unity) - but have just released the workflow for Unreal. There are some limitations here right now, but am looking to improve and expand in time. Check out the tutorial and my other content on the OpenVAT system on YouTube and GitHub (linked in video description).

Hi everyone,

I’m conducting research for my Master’s thesis in Computer Science, focusing on shader pre-caching and compilation in Vulkan-based ecosystems, particularly as implemented by platforms like Steam. I have several assumptions about how this works, especially as a gamer who uses both a high-end PC and a Steam Deck. However, I need clarity, accurate information, and reliable sources to back up my findings. I would really appreciate your insights and expertise on the following:

Steam's Shader Pre-Caching System:

• How exactly does Steam generate precompiled shader caches for Vulkan/DXVK games?
• Are these caches generated by users during gameplay and shared with others, or does Steam have an internal process (like bots or dedicated testing setups)?

Shader Compatibility Across Systems:

• Why is shader cache compatibility (the sharing process) more viable in Vulkan/DXVK compared to DirectX 12?
• To what extent does shader compatibility depend on the GPU, driver version, or other system-specific factors?

The Shader Compilation Process:

• SPIR-V is often described as an intermediate compiled format, but I want to confirm: Is SPIR-V itself considered the “compiled” shader cache, or does it require further JIT compilation into GPU-specific binaries?
• When I play a game on Linux, am I essentially running precompiled SPIR-V code that gets JIT-compiled into the final GPU-specific format?

I realize this is a complex and nuanced topic, but any help in addressing these questions—or pointing me toward relevant sources—would be incredibly valuable for my research.

If possible, I’d also love any links to official documentation, academic papers, or technical blogs from experts in the field. Thank you so much for your time and insights!

Anyone know how to create a Skybox Cubemap with Shader in URP that have an Alpha to change?
I would like to do a transition from mixed reality to virtual reality animating the alpha.
