Shaders/Before 1.9

Shaders are a feature used for various effects in Spectator Mode when the player takes the viewpoint of a mob. Shaders can be disabled by switching the perspective to third-person view. Shaders do not work on computers that do not support OpenGL 2.1, as GLSL (OpenGL Shading 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 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.

Shaders[]

Name	Description	Sample Images
Default (Blit)	This does not utilize shaders. Use as a baseline for comparing to the screenshots below.
Notch	Uses 8-bit color with half the resolution, with a dithering effect. This is a reference to how many of Notch's other games use a similar overlay.
FXAA	This shader adds a small amount of anti-aliasing (smoothing jagged edges), most visible in trees along the horizon.
Art	Pixels are blurred outward, causing moving objects to twinkle.
Bumpy	Outlines color differences, and gives textures a 3D look. (More visible when viewing screenshot at full resolution.)
Blobs2	Similar to Art, but less graphically intensive.
Pencil	Meant to give the world a pencil-sketch appearance.
Color convolve	Intensifies/adds more colors, adding vibrancy.
Deconverge	Offsets the red, green, and blue color channels.
Flip	Flips the player's view vertically.
Invert	Inverts and slightly desaturates colors, obtainable with /gamemode spectator, then spectating from the viewpoint of an enderman.
NTSC	Gives the player's view the impression of a CRT Monitor/Television Screen.
Outline	Outlines color differences similarly to Bumpy, but less complex. Has no effect on some computers.
Phosphor	Pixels on screen linger, being "dragged out" when in motion before fading away.
Scan pincushion	Similar to NTSC, but without the blurring and much less graphically intensive.
Sobel	Turns the view black except for the edges of textures.
Bits	Lowers the resolution and uses an 8-bit color scheme.
Desaturate	Reduces intensity of colors drastically, causing, as the name suggests, a desaturated effect.
Green	Scan Pincushion and Bits, but with a green overlay.
Blur	Blurs the screen overall, independent of what is being displayed.
Wobble	Colors cycle through the hue range constantly. All displayed pixels move up and down via a sine calculation. It should be noted that this affects only the screen plane and not the vertices being displayed by it, as observing the edge of the screen reveals the pixels being moved.
Blobs	Similar to Blobs2 and Art, but the spots are tiny when close up and big when far away.
Antialias	Blurs the edges of pixels to reduce jaggedness. This is blurrier than FXAA, but is better at eliminating jagged edges in textures and blocks.
Creeper	Similar to Green, but with no black borders or low resolution, obtainable with /gamemode spectator then Spectating from the viewpoint of a Creeper or Charged Creeper.
Spider	8 "eyes" onscreen with blur in between, similar to a spider's face, obtainable with /gamemode spectator then Spectating from the viewpoint of a Spider, Cave Spider or Spider Jockey.
Love	Adds a red tint to everything. Used in the Love and Hugs april fools snapshot. This shader is not available using the Super Secret Settings.
