Hey i started working on this bathroom and i wanted a good render before i continue, but for some reason the renders seem to have loads of grain and iv'e tried loads of different types of settings with Vray 1.5 RC3 but it just aint helpin at all. MY Settings Are:
Default Lights Off
Adaptive QMC
Mitchell-Netravali
Vray GI - On, Irradiance Map/ Light Cache, Primary and Secondary Bounces on 0.8
Irradiance Map - High, Hsph. subdivs = 70
Light Cache =
Subdivs - 1200
Sample size - 0.006
Pre-filter - On , 1000
Caustics Off
Enviroment On, 0.3 Value
Refractions On 1.0 Value
Color Mapping - Type = Exponential,
1.8
1.0
1.0

I just dont know whats wrong.Any help would be appreciated.
Thanks

Oh and im using a Vray Sun:
Turbidity = 3.0
Ozone = 0.35
Intensity Multiplier = 0.04
Size Multiplier = 1.0
Shadows Subdivs = 8
Shadows Bias = 0.2
Photon Emit Radius = 0

And heres a greyscale render

Hello. if you mean the grain in the reflective materials then you should add more subdivisions to them. You can do the same with the shadows if you want, but remember that many subdivs will slow down the render.
Good luck
