Hi, i heve problem with shadows
1. shadow is a normal
2. shadow is very darkness
i use vraysun+hdi+vraycam
10x in advance
How does it look if you render without GI?
I think that the (1) shadow is brigher because light is bounced from adjacent parts of the building onto the wall.
Best regards,

Case resolved already

10x - yes this is from GI and some mistake in vraycamera settings
Its not a mistake - the 1 you circled is brighter because of the light bouncing off the opposite wall which is out of shot.
