Resolution Notes
Description
Steps to reproduce:
Download and open the attached project (Fireflies-Bug.zip)
Open SampleScene
Navigate to Lighting window (Window > Rendering > Lighting)
Make sure that Filtering field is set to None
Generate lighting
Observe the noise/fireflies
Notes:
Reproduces in URP and HDRP by default; reproduces in BiRP when using custom light falloff scripts
Reproduces in all Unity editor versions
Reproduces both with CPU and GPU lightmappers
Fireflies eventually go away when using really high sample counts; this extends bake times considerably
