Sun Light "feeling"

Take a look this picture

some people told me that the sun light is different
as usual i’ve some problem with vray settings :roll:
probably the environment (rgb:204.229.255 @ 1.0) is more stronger than the sun light
so this render doesn’t seems too real.


The sun Light is a DirectSpot (254.252.230 @ 1.7)

the GI settings are at default (Medium)
HSph. subdiv 50
Interp sample 20

primary (Irradiance map)
secondry (light map)
