<p>This is the beauty of open source in action - everyone can benefit. Valve are no stranger to open source, and as it turns out they're using a little bit of code from <a href="https://godotengine.org/" rel="noopener nofollow" target="_blank">Godot Engine</a> now too.</p>
<p>Spotted by a few eagle eyes in the recent <a href="https://www.gamingonlinux.com/2025/02/team-fortress-2-major-update-released-and-source-available-for-modders-via-the-source-sdk/" rel="noopener" target="_blank">big Source SDK update that gives the code for Team Fortress 2</a> for modders, the official Valve GitHub page actually <a href="https://github.com/ValveSoftware/source-sdk-2013/blob/0759e2e8e179d5352d81d0d4aaded72c1704b7a9/src/materialsystem/stdshaders/common_lightmappedgeneric_fxc.h#L153C4-L153C25" rel="noopener nofollow" target="_blank">notes</a> that "Bicubic lightmap code lovingly taken and adapted from Godot" (with the Godot license also <a href="https://github.com/ValveSoftware/source-sdk-2013/blob/0759e2e8e179d5352d81d0d4aaded72c1704b7a9/thirdpartylegalnotices.txt#L890" rel="noopener nofollow" target="_blank">noted</a>).
