Shader DevTools

Client-side fabric mod for working on Minecraft core shaders, post shaders, post effects, and render pipelines without restarting the game or reloading the resource pack.

https://github.com/seailz/shader-devtools

Features

• Reload shaders, both core and post, on demand without having to fully reload the resource pack
• Live editing of shader files in-game with syntax highlighting
• When a shader exists in multiple packs (including vanilla), ability to edit each of those individually (except vanilla shaders, which are read-only) and force load them
• Ability to quickly visualize what a shader is rendering
• Parsing of post effect JSON files, and the ability to edit these too
• Parsing and visualization of all render pipelines
• Ability to override any value in the Globals uniform buffer

Shader Debug Logging

You can add calls like dbg("time=" + GameTime); to supported shader programs and the value will be written to logs/latest.log.

Notes:

• Works on both OpenGL and Vulkan
• ASCII string literals are supported
• Top-level string concatenation is supported, so "abc" + someValue works
• Common scalar and vector values are converted to text automatically

Warning:

• dbg(...) is still expensive in hot shaders, especially fragment shaders
• Frequently changing values such as GameTime can reduce FPS if logged aggressively
