What is a PSSL file?
A PSSL file is a shader file used by a PlayStation video game. If encountered in a binary format, the file contains binary code used to produce in-game shading, lighting, and other VFX effects. If encountered in a text format, it includes text source code that is meant to be compiled to binary. The code that PSSL files include is written in the PlayStation Shader Language (PSSL).
More Information
Shaders are programs that produce lighting, shadows, and other special effects in 3D video games and other applications. Since the release of the PS4, PlayStation video games have used shaders written in the PlayStation Shader Language.
For the most part, PSSL shaders follow the same conventions as shaders used for PC games. The PSSL language includes support for vertex, pixel, geometry, and compute shaders, as well as static and dynamic control flow.
How to open a PSSL file
Most gamers will never encounter PSSL files, so no known programs specifically support them. However, those who encounter text-based PSSL files can open, examine, and edit them in any text editor, such as Microsoft Notepad (Windows), Apple TextEdit (Mac), or GitHub Atom (cross-platform).
