Lets make Lightmass EPIC (and understandable)

Hi, I’ve been doing some tests with 4.11, and unfortunately I’m getting some weird stuff in my results, I wouldn’t say they’re light leaks so far, but they’re anomalies in the lighting nertheless.

As you can see, the shadows suddenly ‘choke’ in some spots near the edges.

I’m using the medium preset.
These are my lightmass settings:

And the .ini changes are only these:
NumHemisphereSamples=64
IndirectPhotonDensity=2000
IndirectIrradiancePhotonDensity=1000
IndirectPhotonSearchDistance=180
RecordRadiusScale = 0.12

Besides the artificial lights that were already in the scene, the only change I made was swapping the skylight with a directional light that shines diagonally down into the opening.
Also, adding a portal to the opening where light shines in from changed nothing, apart from making the baking time 3x longer :0

Also, the shadows are kinda… weird? At every corner they are there, looking like outlines, making the scene look cartoonish, it definitely doesnt look like something I would get from a vray render, for instance. Is there a way to fix this?

You are supposed to reduce the smoothness if you raise the quality (especially to 10) not raise it. Try with .75 smoothness.
