About Procedural Texture Online
Procedural Texture Online (ProcTexture) is a free, browser-based platform offering 260+ procedural texture generators for 3D artists, game developers, architects, and VFX professionals. Our mission is to make high-quality, seamless PBR material creation accessible to everyone — no software installation, no account registration, no usage restrictions.
What We Build
We develop procedural texture generators that run entirely in your browser using WebGL shader technology. Each generator produces four physically-based rendering (PBR) maps — Base Color, Normal, Roughness, and Height — that tile seamlessly at any resolution up to 4096×4096 pixels. Our generators cover 32 material categories including architectural surfaces (brick, concrete, marble, tile), natural materials (rock, sand, wood, lava), fabric and textile patterns, metallic effects, organic textures, sci-fi panels, food surfaces, and mathematical noise functions. Every texture is free for both personal and commercial use with no attribution required.
Our Technology
The platform is built on modern web technologies: Next.js for server-side rendering and static generation, WebGL 2.0 for GPU-accelerated texture computation, and a custom GLSL shader pipeline for real-time procedural generation. The mathematical algorithms behind our generators are based on established computer graphics research — Perlin noise (Ken Perlin, 1983), Simplex noise, Worley cellular noise, fractal Brownian motion, and domain warping techniques. Our PBR output follows the industry-standard metalness/roughness workflow compatible with Blender Principled BSDF, Unreal Engine, Unity HDRP/URP, V-Ray, Arnold, Corona, and all other physically-based rendering engines.
Our Expertise
Our team combines experience in computer graphics programming, procedural content generation, and 3D production workflows. We maintain deep familiarity with the PBR rendering pipeline across major engines — understanding how each channel (Base Color, Normal, Roughness, Height) is interpreted by different shading models allows us to produce generators whose output works correctly across all target platforms. Our content draws on years of hands-on experience with Substance Designer, Blender, Unreal Engine, and Unity material systems.
How It Works
Every generator runs a custom GLSL fragment shader on your GPU, computing texture data in real time. As you adjust parameters, the shader recalculates all four PBR channels simultaneously — you see the result instantly without waiting for a server round-trip. The seamless tiling is mathematically guaranteed by the algorithms, not achieved through post-processing blending. Our export system packages the four maps as standard image files (PNG/JPG) ready for direct import into any 3D application. The entire workflow — from opening a generator to having production-ready PBR maps — takes under 60 seconds.
Content Quality Standards
We maintain rigorous quality standards for every generator we publish. Each texture is evaluated for physical plausibility (do the PBR channels tell a consistent physical story?), tiling correctness (is the seamless repeat truly invisible at all scales?), parameter range validity (do extreme parameter values produce usable results?), and production relevance (does this material serve a real workflow need?). Our educational content — guides on PBR theory, normal map usage, and texture workflows — is written from direct production experience, not aggregated from secondary sources.
Free and Open
All textures generated on this platform are completely free for personal and commercial use. There are no watermarks, no attribution requirements, and no restrictions on how you use the exported maps. We believe that accessible, high-quality tools make the entire 3D community more productive. The platform is available in 7 languages (English, 中文, 日本語, Русский, Español, Français, Deutsch) and works on any modern browser without plugins.
