Uses a light tree to more effectively sample scenes with many lights. This can significantly reduce noise, at the cost of a somewhat longer render time per sample. Light tree sampling is enabled by default. It can be disabled in the Sampling > Lights panel. Scenes using light clamping or ray visibility tricks may render different as these are biased techniques that depend on the sampling strategy. The implementation is currently disabled on AMD HIP. This is planned to be fixed before the release. Implementation by Jeffrey Liu, Weizhen Huang, Alaska and Brecht Van Lommel. Ref T77889
