About Bio Rust

Bio Rust is a free digital art technique library. It has, in one form or another, taught people to draw and paint since the mid two thousands, when it was one of the early homes for character art and studio tutorials on the web. This is that library, kept alive and rebuilt for the artists using it now.

A short history of the library

Bio Rust began in the mid two thousands as a small tutorial site, written by artists teaching themselves digital painting while the tools were new. The pages were plain: a method, a few scans of work in progress, the settings used. That plainness made them worth linking to.

One page carried further than the rest. The anime eye tutorial was passed around forums and art communities until hundreds of art sites linked to it, and for years it was the page most people meant by the site's name. It still lives at the same address, rewritten for current tools, as how to draw anime eyes.

The downloads section came next: free brushes, textures and palettes given away without an account or a mailing list. They are the ancestors of the current free brushes and resources library, where the packs are being finalized for public release and each page already explains what the set is for.

Then the site went quiet. Updates stopped after the original maintainer moved on, and for years the address sat unmaintained while the old links kept pointing at it. In 2026 the library was rebuilt. It kept the two-word name, kept the URLs other sites had linked to so that nothing cited would break, and rewrote every method to the standard set out on the editorial method page.

What we are

A calm, technique first reference. Not a course to buy, not a feed to scroll, not a marketplace. Five pillars of craft: character and anime art, digital painting, process and provenance, free brush resources, and a growing archive of tutorials, each written to be read in a few minutes and applied immediately.

What the four pillars cover

Character and anime art is construction: head proportions from any angle, eyes that sit in the skull, hair drawn as blocks before strands, in an order of decisions that holds together when the angle changes.

Digital painting covers the fundamentals that survive every style and app: values before color, hard and soft edge control, and blend modes used for shading rather than decoration. Read it when your drawings are sound and your paintings still look flat.

Process and provenance is the newest pillar and the one working artists ask about most: keeping a process record, attaching and reading Content Credentials and image metadata, checking where an image came from, and what to do when a detector or a stranger says your work was generated.

Free resources holds the brush sets, texture packs and palette collections, each with a page on the settings that matter and a short workflow. The tutorials archive lists every method across the four pillars in one place.

Made by hand

Everything here is built on a single conviction: that human creative skill has value, and that the value does not disappear because a machine can now generate a picture. A generated image has no hand behind it that can change it, no eye that knows why it works. Those are still earned the old way. So Bio Rust teaches the old way, plainly and for free.

This is not hostility to new tools. It is a preference for craft, and a place for the artists who share it. If you want to actually make the thing, with your own hand and your own judgement, this library is for you.

How it is written

Every technique is written as a method: a repeatable order of decisions, so that the hard part moves out of the moment and into the habit. Where a step needs a specific tool named, it is named. Where it does not, it is kept tool agnostic, because the craft outlives any one app.

What Bio Rust is and is not

What the library is, set against what it is often mistaken for.

Bio Rust is	Bio Rust is not
A free technique library, read without an account, an email address or a cookie	A course, a membership or a marketplace
Written and tested by working artists and signed by the studio as a group	The work of one named personality or an anonymous content farm
Tool agnostic where the craft allows it, specific where a step needs it	A manual for one app or an endorsement of one vendor
A place that teaches how to keep, attach and read a process record	A verification service that can certify an image as hand made
Measured only by cookieless analytics that count page views in aggregate	A site that sets cookies, profiles readers or sells advertising inside tutorials
Honest about its own imagery: the header still lifes are generated and disclosed	A gallery of generated images presented as technique or as anyone's artwork

How to use the library well

Read in order the first time. Start with the pillar hub for the skill you want; each hub sets out a reading order and says what each tutorial gives you. Within a tutorial, read the direct answer at the top, then work the numbered steps at the canvas with the page open. Skipping straight to the steps works once. Reading the reasoning is what makes the method stick.

Keep a process record as you go: roughs, named layers and dated session files, as set out in how to document your art process. The record shows your progress across months, and it answers a provenance question before it is asked.

When a page is wrong, say so. Corrections go to hello@biorust.com, are checked at the canvas, and change the page in place.

Why provenance is part of the craft now

Artists today are regularly asked to prove that their work is their own. That is why the library now includes a pillar on process and provenance: how to keep a record of your process, what embedded data and provenance standards can show, and how to judge an image fairly. It is the same made by hand conviction, applied to the questions working artists are actually facing. The longer argument is in what hand technique teaches that generation cannot.

Who writes and reviews the tutorials is described on the studio and editors page. How pieces are researched, checked, and corrected is set out in our editorial method, and questions or corrections can always go to the Bio Rust studio by email. If you are looking for a specific technique, search the library.

The promise. Free to read, free to use, no account, no email. Just the techniques, taught by people who draw.
