An open library for technical art

A lot of great technical art is shared openly on GitHub, but it's scattered across thousands of repositories with inconsistent READMEs and few screenshots. Open Tech Art collects the good, openly licensed work into one consistent, searchable catalog, and it always sends you back to the repository and the people who made it.

What this is — and isn't

Open Tech Art is a curated resource library, not a marketplace. Nothing here is for sale, there are no ratings or paid placements, and there are no accounts. Every entry points to a public GitHub repository. For each one we add discovery, consistent metadata, screenshots, categorisation, compatibility notes and a clear link to the original project.

The library starts with Unity URP shaders and rendering techniques, especially Shader Graph. The content model is deliberately broader, so VFX, lighting setups, impostor systems, reference scenes, editor tools and other engines can be added without restructuring.

Selection criteria

• The project lives in a public GitHub repository.
• It is free to obtain.
• It has an explicit open license that allows use and the display of its screenshots, such as MIT, BSD, Apache 2.0, CC0, CC BY or the Unlicense. Free of charge is not the same as open, and anything with ambiguous terms is left out.
• The creator provides screenshots that we are allowed to show.
• Compatibility is recorded only as stated by the creator or evident from the project.

Every entry has a catalog record: the date it was checked, the revision that was checked, and notes on how. If something has changed upstream, pleaseopen an issue or edit the entry directly.

Stars, updates and featured picks

Each entry shows its repository's GitHub star count and the date of its latest commit, so you can tell at a glance whether a project is popular and still maintained. You can sort the catalog by either. Featured picks combine the two: well-starred repositories rank higher, and that score fades the longer a repository goes without a commit. These numbers are refreshed by a maintainer running a script, so they can be a little behind GitHub.

Raw → Reference → Showcase

Our long-term image standard has three parts:

• Raw shows what goes in: the geometry or input without the technique.
• Reference shows what the technique itself does, under simple, honest conditions.
• Showcase shows what can be achieved with it in a polished scene.

Resource pages can already show Raw and Reference side by side or with a comparison slider. The first seed entries were collected from the web, so they use the creators' own screenshots. We never manufacture missing images. Unusual techniques sometimes need exceptions, because honesty and clarity matter more than rigid standardisation.
