Luoshuang's GPULightmass

Did some experiments with Prometheus, very nocticable overall quality improvement in comparison with previous GPU Lightmass even on Unified settings. 99% dark corners free.
I have couple questions:

1. Old GPU Lightmass plugin had only Num Indirect Bounces setting possible to change, will new Prometheus respect other Lightmass Settings, like Static Lighting Level Scale or Num Sky Lighting Bounces?

2. Will it be possible to change the baking quality (Preview, Medium, High etc.) on the fly with no need to restart the editor?

3. Any info about ETA ?

1. Static Lighting Level Scale is a parameter for the old school irradiance caching, which is the source of large splotches and seams between modular pieces, thus has been abandoned; Num Sky Lighting Bounces is respected by CPU Lightmass because it runs separate passes for sky lights and other lights, however GPULightmass has only one unified secondary GI pass thus it is not practial.

2. With 4.21 Unified settings you can already do that by modifying BaseLightmass.ini

3. No idea, even me don’t know when I can finish it :o

Regarding the ‘seemingly’ dark corners in the images, can you check whether the wall’s UVs are detatched? If a texel expands over the corner it will be inevitably dark due to the limitations in UE4’s ‘spherical harmonics’.
