The code it becomes

What Studio writes for the graph below: a few lines of the material's shader, worked out for every pixel.

void mainImage(out vec4 fragColor, in vec2 fragCoord){    float n2_alpha = smoothstep(0.3, 0.3 + 0.1, distance(vec3(0.0, 1.0, 0.0), vec3(0.0, 1.0, 0.0)));    fragColor = vec4(vec3(n2_alpha), 1.0);}

In a graph

Texture coordinates into the node, and the node into the material, as Studio draws them.
