Hi!
With these setting right now you have just 1 bounce of skylight and have a directional light which bounces “randomly”.
- with the high smoothness setting you wash away your details…
I wouldn’t go higher than 10 in the bounces and would set the skyligh bounce to the same setting!
Smoothness I would go with 0.6 to get better shadow details. I wouldn’t use ambient occlusion until you’re happy with your clean lighting…
I wouldn’t change anything in baselightmass.ini…
Are you using any color grading or heavy post processing? Usually that’s when I get those (contrast)
