Shadertoy to Unity shader converter

Online demo here (pema99.github.io/glsl2hlsl)

glsl2hlsl

Slightly cursed WIP ShaderToy to Unity (ShaderLab) transpiler.

Sorry if the code gives you an aneurism.

Features

• Converts a fairly decent chunk of shadertoy shaders to usable unity shaders
• Can attempt to automatically find and extract properties from the shader and put then in the inspector
• Can attempt to automatically make raymarched/raytraced shaders 3D
• Can download shaders directly from the shadertoy API given a link
• Synthesizes a usable unity material and .meta file when using download feature

Some cool shaders to try it on

Fractal land by Kali

Protean clouds by IQ

Fractal pyramid by bradjamesgrant

Phantom star by kasari39

To do

• Better support for preprocessor directives in any context
• Multiline macro support
• Implement various missing sampler-related functions such as textureSize, textureLodOffset etc.
• A few properties defined by shadertoy (iDate, iChannelResolution...) are missing
• Refactor
