In your case you can make this function. vec4 get_gradient_color(float position) { return texture (sampler, vec2 (position, 0.5 )); } And then get colors with get_gradient_color (0.8), where 0.8 is position on image between 0 and 1. WebMm so there's learning about shaders and there's learning about ray-marching.

In particular, Write the tint color like this: uniform vec4 tint_color: hint_color = vec4 (0.0, 0.5,0.99, 1); So Godot gives you a color picker in the shader parameters. See Uniforms. You could also use hint_range (0, 1) for amp. However, I'm not sure about that. Double check your coordinates.
