Source Water is an independent, non-commercial fan project.

## Valve Source Engine references and assets

The water implementation was developed by studying and reverse-engineering Source Engine revisions from 2004 and 2007. Portions of the behavior are adaptations of algorithms documented in Source SDK shader code.

The following textures are derived from Valve Source Engine water normal maps and are not covered by the project's WTFPL:

- `shaders/textures/water_normal/mip0.frame0.png`
- `shaders/textures/water_normal/atlas.png`

Valve Corporation retains all rights to its original code, games, names, and assets. Consult the [Source 1 SDK License](https://github.com/ValveSoftware/source-sdk-2013/blob/master/LICENSE) and [Steam Subscriber Agreement](https://store.steampowered.com/subscriber_agreement/) before redistributing or using Valve-derived material. In particular, Valve's published developer-tool and fan-content terms are non-commercial.

## Iris example shader pack

The project started from the Iris example shader pack and XorDev's Default Shaderpack. The inherited files state that they are free to use, with credit appreciated.
