Lets make Lightmass EPIC (and understandable)

[anonymous_user_f2b8b290]

I have now checked in my Lightmass solver quality improvements:
A) Adds light portals - these solve static skylight quality in highly enclosed areas like the example
B) Fixed high IndirectLightingQuality settings disabling adaptive sampling - this improves static skylight quality
C) Fixed light leaks when using spotlights with StaticLightingLevelScale .1 - StaticLightingLevelScale is no longer applied to photon emission

These changes will be in 4.11 which will probably be in about 4 months.

So to wrap up 's original post

1. How to remove the splotches in the area where there is no skylight hitting directly (Areas far from windows). As you can see in the above images there are so many splotches in gallery, despite having Indirect Lighting quality to = 10 and static Lighting Level scale = .1
2. Shadows become somewhat messy after a certain distance. How to make area shadows more clear and smooth.

This is addressed by A) + B)

3. Whenever we put spotlights to remove dark areas, it almost always gives the annoying problem of light leaks. Clearly evident in the above images.

This is addressed by C)

Sadly that’s all the time I can spend on Lightmass atm, otherwise I would like to investigate some more complex scenes.
