Shaders/Before 1.9

Shaders are a feature being tested in the 1.7.2 update. You can switch between them by pressing the "Super Secret Settings..." button under options in the menu, although it doesn't work for some people. Shaders can be disabled by pressing the F4 key. Shaders may not work in computers that do not have OpenGL 2.1.

Shaders are stored in the assets/minecraft/shaders/ directory of minecraft.jar. The file path of the currently-active shader is displayed on the debug screen.

Note that the differences between certain shaders can be very subtle, and therefore, to notice the differences, it might be necessary to observe a picture with higher resolution by pressing one of the pictures below.
