Vray Light noise

[elmago1]

Hi, I have a problem with light noises on my windows. Denoiser option in render element couldn’t help me that much.

My primary light is dome without HDRI, secondary light vray plane and some additional fill lights with low power.

 

I have tried to set the subdivs to 16/32 for all lights and materials, Played with the noise threshold values and bucket image smapler, but the problem is still not solved.

 

This is my render setting using Vray Next 4.1:

 

Image sampler: bucket, max subdivd 2/8, noise threshold 0,005

GI: Irradiance map + light cache

Irradiance map: High, subdivs 40, interp. Samples 60

Light cache: 1500

Subivs materials and lights: 16

 

Can anyone help me please?
