Injecting GPL code into games #202

Open capnm opened 5 years ago

capnm commented 5 years ago

Currently the GPL licensed shader code e.g. https://github.com/godotengine/godot-blender-exporter/blob/master/tests/reference_exports/material_cycle/material_anistropy.escn may land in the exported game.

I am not a lawyer, but theoretically this could be an issue for someone publishing a commercial (closed source) game made with Godot. Here I found some discussions on the topic: https://opensource.stackexchange.com/questions/2501/does-using-a-gplv2-code-generator-force-my-project-to-be-similarly-licensed

The #87 is also related. It would be nice if someone could bring more clarity. @akien-mga what do you think?

The shader code could be MIT-licensed to avoid this. The MIT license is GPL-compatible, which means it can be used in GPL-licensed software without trouble.
