A custom node for ComfyUI that allows you to render GLSL shaders (Shadertoy-style) directly inside your workflows. (Description by CC)
👾 ComfyUI ToyShaders
ToyShaders is a custom node for ComfyUI that allows you to render GLSL shaders (Shadertoy-style) directly inside your workflows. It supports internal textures, multipass rendering, presets, animated previews and automatic depth map output.
✨ Features
Shadertoy-style GLSL rendering inside ComfyUI
Multipass support (Buffer A + Main Image)
Built-in procedural textures (noise, clouds, wood, checkerboard, etc.)
Optional external textures via iChannel0–3
Automatic preset discovery from the shaders/ folder
Animated WebP preview output
Automatic depth map generation using a custom variable
Clean separation between rendering backend and UI node
✔ Option 2 — Manual Installation
git Clone this repository into:
ComfyUI/custom_nodes/ Install requeriments.txt
Then restart ComfyUI.
🗂 Shader Presets
Download new shaders from https://www.shadertoy.com/
You can place .glsl or .txt shader files inside:
ComfyUI-ToyShaders/shaders/
They will automatically appear in the preset selector inside the node.
This allows you to build your own library of shaders or reuse Shadertoy-style code with minimal adjustments.
🧪 Dependencies
🛠 Quick Usage Guide, test the sample workflow
Add the ToyShader Render node in ComfyUI.
Select a preset or paste your own GLSL code.
Optionally add a Buffer A shader for multipass effects.
Tune parameters like:
speed
scale
internal texture selection
depth variable & depth scaling
The node outputs:
RGB animation frames
Depth map (3-channel grayscale) - EXPERIMENTAL

This project brings the expressiveness of Shadertoy into ComfyUI’s node-based workflow. Have fun creating procedural graphics, loops, VFX and experiments directly inside the AI pipeline!
