Properties

Script (FragmentShader)

The GLSL fragment shader source.

• Type: string
• Default:

  #version 450
  
  layout(location = 0) in vec2 fragCoord; // 0.0 - 1.0
  layout(location = 0) out vec4 outColor;
  
  layout(set = 0, binding = 0) uniform sampler2D srcTexture;
  
  layout(push_constant) uniform PushConstants {
      float progress;   // 0.0 - 1.0
      float duration;   // seconds
      float time;       // seconds
      float width;      // render target width
      float height;     // render target height
  } pc;
  
  void main() {
      vec4 c = texture(srcTexture, fragCoord);
      outColor = c;
  }

• Animatable: No

Usage

Provide a fragment shader that writes the output color from the input source texture and any animatable uniforms.
