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); vec3 n2_colour = (lib_layer(vec2((n1_uv).x, 1.0 - (n1_uv).y))).rgb; float n2_r = (lib_layer(vec2((n1_uv).x, 1.0 - (n1_uv).y))).r; float n2_g = (lib_layer(vec2((n1_uv).x, 1.0 - (n1_uv).y))).g; float n2_b = (lib_layer(vec2((n1_uv).x, 1.0 - (n1_uv).y))).b; float n2_alpha = (lib_layer(vec2((n1_uv).x, 1.0 - (n1_uv).y))).a; vec4 n2_rgba = lib_layer(vec2((n1_uv).x, 1.0 - (n1_uv).y)); fragColor = vec4(n2_colour * clamp(n2_alpha, 0.0, 1.0), 1.0);}In a graph
