GodRays

The GodRays effect requires a mesh that will be used as an origin point for the rays. Refer to this example for more details.

import { GodRays } from '@react-three/postprocessing'

return (
  <GodRays
    sun={sunRef}
    blendFunction={BlendFunction.Screen} // The blend function of this effect.
    samples={60} // The number of samples per pixel.
    density={0.96} // The density of the light rays.
    decay={0.9} // An illumination decay factor.
    weight={0.4} // A light ray weight factor.
    exposure={0.6} // A constant attenuation coefficient.
    clampMax={1} // An upper bound for the saturation of the overall effect.
    width={Resizer.AUTO_SIZE} // Render width.
    height={Resizer.AUTO_SIZE} // Render height.
    kernelSize={KernelSize.SMALL} // The blur kernel size. Has no effect if blur is disabled.
    blur={true} // Whether the god rays should be blurred to reduce artifacts.
