Description
CanvasGLSL
Replace Minecraft's menu backgrounds with custom GLSL shaders. Includes a built-in shader editor with syntax highlighting.

- Live shader editor (press
Insertto open) - Works on all menu screens (title, singleplayer, multiplayer, options, etc.)
- Shadertoy compatible - paste shaders directly from Shadertoy
- Auto-compile or manual compile modes
- File manager for organizing shaders
- Syntax highlighting
Installation

- Download the latest release JAR
- Put it in your

Usage
Opening the Editor
Press Insert while in any menu to open the shader IDE. Press Insert or Esc to close it.
Writing Shaders
Shaders are saved in .minecraft/canvasglsl/. You can create folders to organize them.
Supported uniforms:
uniform float iTime;- Time in secondsuniform vec3 iResolution;- Screen resolution (width, height, aspect)uniform vec4 iMouse;- Mouse position (x, y, click x, click y)uniform int iFrame;- Frame counteruniform sampler2D iChannel0;- Procedural noise textures (iChannel0 through iChannel3)uniform float iTimeDelta;- Time since last frameuniform vec4 iDate;- Current date/time (year, month, day, seconds)uniform float iSampleRate;- Audio sample rate (44100)
Example shader:
void mainImage(out vec4 fragColor, in vec2 fragCoord) {
vec2 uv = fragCoord / iResolution.xy;
vec3 col = 0.5 + 0.5 * cos(iTime + uv.xyx + vec3(0, 2, 4));
fragColor = vec4(col, 1.0);
}
Using Shadertoy Shaders
- Copy shader code from Shadertoy
- Paste into the editor
- Click "Compile" or enable auto-compile
- Done! The shader will render as your menu background
Controls
Insert- Toggle shader editorEsc- Close editorCtrl+S- Save current shader- Compile button - Compile shader manually
- Auto-compile toggle - Auto-compile on save
