Shaders/Before 1.9

Shaders are a feature being tested since the 1.7.2 update. You can switch between them by pressing the "Super Secret Settings..." button under options in the menu. Some shaders are used for various effects in Spectator Mode when the player takes the viewpoint of a mob. Shaders can be disabled by pressing the F4 key or by cycling the Super Secret Settings button until the game returns to unshaded mode. Shaders will not work in computers that do not support OpenGL 2.1, as GLSL (OpenGL's shader language) was introduced in OpenGL 2.

Currently, 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 clicking on one of the pictures below.

Repeatedly clicking the "Super Secret Settings..." button will cycle through the shaders in the order listed below.
