Weizhen Huang commented on issue blender/blender#108505 2023-07-07 18:56:24 +02:00
Fix wrong conversion between power and radiance of emitters

The factors are corrected in various commits listed above. To summarize:

Area Light

Using a factor of 1/(\pi A), as computed above.

Sphere Light

Using a factor of 1/(4\pi^2r^2),…
