hi cgtalker,

i need your help to improve a exterior scene i want to do.
I've try to work with VraySun, and create a daylight scene.

I've some difficulties with sun setting and there are few things i don't really understand, maybe your skill could help :)

i don't know why i've the feeling to lose details. :shrug:
i don't understand why some shadows are almost like a "moire" effect. (even if i change the shadow bias)

i know it could be easiest to try a simple vray light setting, but i hate to not understand :D

Setting on vray (1.5) :
- no GI environement skylight
- color mapping : linear multiply 1.0 / 1.0
- filter : mitchell-netravali
- irradiance map preset : medium -animation

Vraysun Parameters :
- turbidity : 2.0
- ozone : 0.8
- intensity multiplier : 0.1
- size multiplier : 0.5
- shadows subdivs : 32
- shadow bias : 0.2m
- photo emitter radius : 0.02m

here the rendered scene :

and here the viewport :

There is something i miss ? :shrug:
