// Replace in code "fragCoord" by "gl_FragCoord"


// Then add at top of code:

layout(location = 0) out vec4 fragColor;

uniform vec3 iResolution;
uniform float iTime;
uniform float iFrame;

// In glsl node:
// Declare iResolution, iFrame and iTime
// For iTime:
absTime.seconds
// For iFrame:
absTime.frame
