V-RAY light reflection noise problems

[lourencobarreto]

Hello everybody.

 

I am having some issues with the reflection using vray 2.0 for rhino.

 

I can't get rid of the noise in the reflection of the materials.

 

I'm using irradiance map as my primary bounces and light cache as the second.

 

I've done some research and as a result of that I'm using sub-pixel mapping and clamp output on the color mapping, the noise got better but it is still there. I've also changed my antialiasing filter from lanczos to area and in the material presets i've changed to treat glossy as GI ALWAYS.

 

Any ideas on how to smooth this noise?

 

Thank you very much.

Anything noise is sample/AA related, you need more samples or you need to lower your noise threshold so V-Ray can use more samples.

Looking at your image I would recommend using color mapping, Reinhard is a good option, set the burn value to 0.4 or so, that will 'clamp' the over bright areas that are the hard to sample.

 

Having said that your image does not look noisy really, what I see is the glossiness over the bumpy texture.
