Couple of things:
you can increase the resolution of the Volume Light Samples by modifying this section of the Lightmass.ini

[DevOptions.PrecomputedDynamicObjectLighting]
bVisualizeVolumeLightSamples=False
bVisualizeVolumeLightInterpolation=False
NumHemisphereSamplesScale=2
SurfaceLightSampleSpacing=100
FirstSurfaceSampleLayerHeight=25
SurfaceSampleLayerHeightSpacing=100
NumSurfaceSampleLayers=4
DetailVolumeSampleSpacing=300
VolumeLightSampleSpacing=3000
; Clamp the number of volume samples generated to ~3mb
MaxVolumeSamples=50000
bUseMaxSurfaceSampleNum=True
; Approximately clamp the number of surface samples generated to ~30mb (only for Landscape currently)
MaxSurfaceLightSamples=500000

The Detail volume basically fills the volume with samples rather than it being a few layers on the ground. You can visualize the samples by going to Show>Visualize>VolumeLightSamples and it looks liek this:

Also, be sure to be using reflection capture actors in your scene. For dynamic objects, they impart lighting information as well as reflection information and can help with the look of exterior lighting leaking in. these ONLY capture static geometry however so if your walls, etc are dynamic they won’t help.

Last thing I’ve learned is to use post process volumes to good effect, especially if you’re using a Skylight (or just don’t use a skylight!)

Look forward to seeing an update!

Hello, guys. (Happy New Year! =D)

I’ve been trying to use this tweak again in the new version of my project. I’ve restored the Lightmass.ini to it’s default settings long time ago after that test because I didn’t need it for a while. Now I need to increase the Volume Light Samples resolution again, but it is not working anymore! There are a lot of Lightmass.ini files in my system, I don’t know exactly witch one affects this very project. Anyway, none of those files seems to have any influence on the project, the Volume Light Samples continues with the same resolution (witch is too low for my purposes).

Does anyone knows how could I increase the Volume Light Samples resolution again?
Thanks in advance!

This parameter is now on WorldSettings -> Lightmass
