Licence & Terms

Licence & Terms

As of v2.2.8, Universal Shader Library is a single free build. There is no paid tier and no commercial subscription — USL is free to use, including for commercial work.

Whether you’re working on a personal portfolio, a paid client project, or a shipped commercial product, you can use USL at no cost. The app stays free for everyone.


What You Can Do

  • Use USL for personal, hobby, and student projects
  • Use USL for paid client work, studio pipelines, and commercial productions
  • Use it across any of the supported DCCs and renderers

No licence purchase, subscription, or registration is required for any of this.


What You Cannot Do

USL is closed-source software. To keep the app free and sustainable, the licence does not permit you to:

  • Redistribute the app or its files (host, share, or bundle it elsewhere)
  • Resell USL or access to it
  • Modify the application
  • Reverse-engineer, decompile, or disassemble it

These terms cover the application itself. For the materials shipped inside USL, see PixelConstruct Materials.


Updated Terms

The Terms of Service were updated in v2.2.8 to reflect the move to a single free build. Existing users will be re-prompted to accept the updated Terms the next time they launch the app. Accepting is required to continue using USL.


Support USL

USL is a solo project and it’s free for everyone — there’s no obligation to pay anything. If it saves you time and you’d like to help fund continued development, you can support it on Patreon. It’s entirely optional and is never a requirement for commercial use.
