How To Import Shader From ShaderToy To Godot

Godot uses it own shader language although quite similar to GLSL it can still be a bit tricky to import shaders from shadertoy which also uses its own variables and techniques , in this tutorial will take the most popular new fragment shader in ShaderToy and import it to Godot making all required conversions slowly step by step.

Nice. Does anybody know how to migrate the Volume 3d Noise?

you will have to be more specific than that

This 3d volume.

If its an image we can use: uniform sampler2D iChannel0 as shader param.

How about the 3d Volume Noises? What kind of file that represent the 32 x32 x32, uint8?

I am not entirely certain, because I am new to this but you can of course work with any kind of data shader wise including 3d arrays using uniforms for input and output. I am also aware about Texture3d for 3d textures. Godot supports this via https://docs.godotengine.org/en/stable/classes/class_texture3d.html

How you could load this from a file, I have no idea, never tried it.
