Backgrounds & shaders guides for AI video

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/api/search?q=<what the person wants>" returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the use-case page.

6 guides for backgrounds & shaders: shader backgrounds, overlays, filters, particles and WebGL effects.

Guides (6)

• PixiJS Blend Modes — PixiJS: Composite PixiJS v8 layers with add, multiply and screen, or advanced modes like overlay and color-burn.
• PixiJS Custom Rendering — PixiJS: Write custom shaders, uniforms and batchers for PixiJS v8 that run on both WebGL and WebGPU.
• PixiJS Filters — PixiJS: Add blur, displacement, color-matrix and custom GLSL/WGSL filters to PixiJS v8 scenes without killing FPS.
• PixiJS Meshes — PixiJS: Deform images with custom geometry in PixiJS v8: meshes, planes, ropes and 2.5D perspective corners.
• PixiJS Particles — PixiJS: Render thousands of lightweight particles in PixiJS v8 with ParticleContainer and dynamic properties.
• WebGPU Three.js TSL — Dan Greenheck, beta: TSL node materials, GPU compute, post-processing and WGSL for three.js WebGPURenderer, by the Three.js Roadmap author.

Other kinds of skills

• Prompts: The words a video model obeys: camera angles, shot sizes, lighting, characters, hooks and prompt guides for Seedance, Kling, Veo, FLUX and Higgsfield. Your agent writes the prompt with them, or you paste them into the model.
• Effects: An effect you can see, added to your video: animated titles, captions, transitions, shader backgrounds, logo animations, device mockups and viral camera tricks. Hand your agent the footage or the brief and get the effect.
• Styles: The look of the whole video: art styles, film looks, color grades and LUTs, caption fonts and style references. Pick a style and every shot your agent makes follows it.
• Workflows: A brief in, a finished video out: UGC ads, product videos, music videos, talking heads, explainers, Shorts and short dramas, step by step, with the models and the edit chosen for you.
• Models & tools: Run one model or tool from your agent: Seedance, Veo, Kling, FLUX, GPT Image, Nano Banana, ElevenLabs and 1,200+ more, plus scrapers, trend search and video analysis.
