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){    vec2 n1_uv = (vec2(fragCoord.x / iResolution.x, 1.0 - fragCoord.y / iResolution.y) * vec2(1.0, 1.0));    vec2 n1_centred = (vec2(fragCoord.x - 0.5 * iResolution.x, 0.5 * iResolution.y - fragCoord.y) / iResolution.y);    vec2 n1_square = (vec2(fragCoord.x, iResolution.y - fragCoord.y) / iResolution.y);    float n2_diffuse = max(dot(normalize(vec3(0.0, 0.0, 1.0)), normalize(vec3((vec2(0.3, 0.3) - n1_uv) * vec2(iResolution.x / iResolution.y, 1.0), 0.3))), 0.0);    float n2_specular = pow(max(dot(normalize(vec3(0.0, 0.0, 1.0)), normalize(normalize(vec3((vec2(0.3, 0.3) - n1_uv) * vec2(iResolution.x / iResolution.y, 1.0), 0.3)) + vec3(0.0, 0.0, 1.0))), 0.0), max(32.0, 1.0));    fragColor = vec4(vec3(n2_diffuse), 1.0);}

In a graph

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