Radiance Cascades Global Illumination (the one that will probably be a part of the upcoming Godot solution, mixed with their Voxel-based HDDAGI).
The initial solution of Radiance Cascades for 3D lighting was created by Path of Exiles 2 developers. And by
Alexander Sannikov, who posted his experiments for the last couple of years.
But this one runs even on a phone. And it's beyond screen space!
