1. In a digital medium environment to render a digital image of a digital scene, a method implemented by at least one computing device, the method comprising:

  • identifying, by at least one computing device, a plurality of light paths between a light source and the digital image to be rendered of the digital scene, each light path of the plurality of light paths having a primary vertex and a secondary vertex between respective segments of the light path;

    generating, by the at least one computing device, a plurality of correlated samples from the light paths, each correlated sample of the plurality of correlated samples based at least in part on similarity of the secondary vertex of respective said light paths to each other; and

    rendering, by the at least one computing device, the digital image of the digital scene based at least in part on the plurality of correlated samples.
