Licence & Terms

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.

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.
