Ok so here is an apples to apples comparison of ****** Mod **and the 4.18 preview.
Skylight only, using an HDRI and 15 light bounces. Static lighting scale of 0.1
ini was modified on both : NumShadowRaysScale=**16 , **NumPenumbraShadowRaysScale=**64 , **NumHemisphereSamplesScale=**32

Mod**: 3 h build time

**4.18 preview ** : 1.5 h build time

's build is much faster, but I feel that 's modded version looks a bit nicer. There is a big difference in brightness although I imagine that Daniels build might play better with sun lighting.

P.S Thank you for your contribution.

What lightmass settings did you use there? That lighting its awesome!!
